CILogon Classic

ECP stands for “Enhanced Client or Proxy”, a SAML v.2.0 profile which allows for the exchange of SAML attributes. Thus, ECP can be very useful for non-browser cyberinfrastructure applications (command-line, thick-client, etc.). Below are a few links describing the ECP profile in detail.To enable ECP in your Shibboleth IdP installation, see:In the ECP profile, both the Service Provider (SP) and the Identity Provider (IdP) must understand the ECP SOAP/PAOS binding. The CILogon Service Provider supports fetching an end-user X.509 certificate using any InCommon-member ECP-enabled IdP.

Note that your IdP must release the attributes required by CILogon for you to obtain a certificate. Please test that your IdP is releasing the needed attributes by visiting https://cilogon.org/testidp/.

A list of InCommon-member ECP-enabled IdPs is maintained on the CILogon servers. If you would like to add your ECP-enabled IdP to this list, please send email to [email protected].

ECP at Fermilab

Fermilab users should use the cigetcert tool to obtain certificates from CILogon using ECP.

ECP for LIGO

LIGO users should use the ligo-proxy-init tool to obtain certificates from CILogon using ECP.

CILogon’s ecp.pl script

ecp.pl – Fetch a certificate from the CILogon Service via ECP

ecp.pl -h

Below is a Perl script which can fetch a certificate or PKCS12 credential from the CILogon Service.This Perl script can be run interactively (where the user will be prompted for all information) or in batch mode (by the use of command line options). Run “” to see usage information.

The script relies on several Perl packages, all of which are available in CPAN or via the package manager for your O/S. If you receive an error message about SSL and Certificate Authorities, you may also need to install the Mozilla::CA Perl module. For example:

$ perl -MCPAN -e ‘install Crypt::SSLeay’ $ perl -MCPAN -e ‘install Mozilla::CA’

The script also requires OpenSSL. If you have installed the openssl binary in a location other than /usr/bin/openssl , you will need to modify the script to point to the location of openssl on your system.

The ecp.pl command-line interface performs HTTP Basic authentication (username/password) with the chosen SAML identity provider (IdP) to obtain a SAML authentication assertion for use with CILogon. CILogon never sees the user's password.The testecp.sh script (modified from the original at shibboleth.net ) provides a basic test for a SAML ECP enabled identity provider. Simply modify the parameters at the top of the script to match your identity provider and service provider configuration. To test your service provider using ProtectNetwork's IdP, you must first register your SP with ProtectNetwork

The SAML V2.0 Enhanced Client or Proxy profile is a SSO profile for use with HTTP, and clients with the capability to directly contact a principal’s identity provider(s) without requiring discovery and redirection by the service provider, as in the case of a browser. This specification updates the original profile by adding support for “Holder of Key” subject confirmation [SAML2HOK] and channel bindings [ChanBind].

This prose specification is one component of a Work Product that also includes:

The SAML V2.0 Enhanced Client or Proxy (ECP) profile is a SSO profile for use with HTTP, and clients with the capability to directly contact a principal’s identity provider(s) without requiring discovery and redirection by the service provider, as in the case of a browser. It is particularly useful for desktop or server-side HTTP clients.

This specification updates the original profile by adding support for “Holder of Key” subject confirmation [SAML2HOK] and channel bindings [ChanBind]. These additions are optional from a deployment perspective, and are incorporated in a backward-compatible fashion for use with existing implementations when the new features are not used. Both features can be used independently or together, to strengthen the security of the profile.

The addition of “Holder of Key” support has been well-motivated by previous work (e.g., [HOKSSO]), and is equally useful here to strenghten the security and widen the applicability of the original ECP Profile. Incorporation of this addition is accomplished in an analagous manner to [HOKSSO], but additional non-TLS (and non-public key) options are permitted to allow for proof of key possession based on XML Signatures [XMLSig] or HTTP-compatible mechanisms that may emerge in the future.

The addition of channel bindings takes advantage of the enhanced client’s capability to intelligently add information to its exchange with the identity provider, in this case channel bindings between itself and the service provider. Combining this with channel bindings transmitted by the service provider in its (signed) message allows the identity provider to perform channel bindings verification on behalf of both parties without introducing a requirement for key management into the enhanced client. This in turn allows the identity provider’s typically strong and flexible authentication of the service provider to supplement (or substitute for) the typically ineffectual authentication that commercial TLS certificates allow the client to perform.

The keywords “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this specification are to be interpreted as described in [RFC2119]. These keywords are thus capitalized when used to unambiguously specify requirements over protocol and application features and behavior that affect the interoperability and security of implementations. When these words are not capitalized, they are meant in their natural-language sense.

Description: Given below.

Updates: The Enhanced Client or Proxy profile in Section 4.2 of [SAML2Prof].

The original Enhanced Client or Proxy Profile [SAML2Prof] is a SAML authentication profile based on the Authentication Request protocol in [SAML2Core]. This profile builds on the original in a backwardly-compatible fashion by adding two additional options:

Channel Bindings

“Holder of Key Subject” Confirmation

Both features are optional additions to the base profile, and use of this profile without either feature is by design wholly compatible with (and indistinguishable from) the original profile. The two additional options are independent and can be deployed together or separately.

The reader may wish be familiar with the original profile, and some of the normative content of this profile makes reference to the original. The steps outlined in the profile overview, Section 4.2.2, in [SAML2Prof] apply equally here.

2.3 Profile Description

The following sections describe each step in the profile. Some of the normative requirements of the original profile are repeated here for completeness, and to improve the technical presentation of the original material, which has proven somewhat confusing to follow. The normative definitions of the various header blocks, and their schemas, can be found in [PAOS] and [SAML2Prof].

In the steps that follow, all SOAP header blocks described by the profile MUST contain actor and mustUnderstand attributes set to “http://schemas.xmlsoap.org/soap/actor/next” and “1” respectively unless otherwise indicated.

2.3.1 ECP Issues HTTP Request to Service Provider

The client makes an arbitrary HTTP request to a service provider for a resource.

To indicate support for this profile, and the PAOS binding, the request MUST include the following HTTP header fields:

1. An Accept header indicating acceptance of the MIME type “application/vnd.paos+xml”

2. A PAOS header specifying the PAOS version with a value, at minimum, of “urn:liberty:paos:2003-08” and a supported service value of “urn:oasis:names:tc:SAML:2.0:profiles:SSO:ecp”. The service value MAY contain option values as follows:

· Support for channel bindings indicated by the option value “urn:oasis:names:tc:SAML:protocol:ext:channel-binding”

· Support for Holder-of-Key subject confirmation indicated by the option value “urn:oasis:names:tc:SAML:2.0:cm:holder-of-key”

· Request for a signed SAML request indicated by the option value “urn:oasis:names:tc:SAML:2.0:profiles:SSO:ecp:2.0:WantAuthnRequestsSigned”

· Request to delegate credentials to the service provider indicated by the option value “urn:oasis:names:tc:SAML:2.0:conditions:delegation”

As defined by [PAOS], service values are delimited by semicolons, and options are comma-delimited from the service value and each other.

A client that supports the Holder-of-Key option MAY utilize TLS client authentication using an X.509 certificate (particularly assuming it plans to do so in subsequent communication with the service provider), but proof of key possession is not formally required during this step.

The example demonstrates a client that supports two of the new options requesting a page. The PAOS header is one continuous line.

GET /secure/ HTTP/1.1

Host: sp.example.org

Accept: text/html; application/vnd.paos+xml

PAOS: ver=”urn:liberty:paos:2003-08″;

“urn:oasis:names:tc:SAML:2.0:profiles:SSO:ecp”,

“urn:oasis:names:tc:SAML:protocol:ext:channel-binding”,

“urn:oasis:names:tc:SAML:2.0:cm:holder-of-key”

If the service provider requires a security context for the principal before allowing access to the specified resource, it responds to the HTTP request in the previous step using the PAOS binding, including a message in its HTTP response.

The HTTP response contains a Status code of 200, and the body consists of a SOAP 1.1 Envelope, which MUST contain the following:

1. A element in the SOAP body. The rules for the request specified in the Browser SSO profile in Section 4.1.4.1 of [SAML2Prof] MUST be followed. If the option for a signed request is set by the client (see Section 2.3.1), then the request SHOULD be digitally signed by the service provider.

2. A SOAP header block element (see Section 10 of [PAOS]). Its content MUST be as follows:

· service MUST be set to “urn:oasis:names:tc:SAML:2.0:profiles:SSO:ecp”

· responseConsumerURL MUST contain an absolute URL that specifies where error responses generated by the client should be sent; it MUST match the value of the AssertionServiceConsumerURL attribute in the (or in its absence the location to which the identity provider is expected to target its response, such as a location derived from SAML metadata).

· messageID MAY be set but is not required

3. An SOAP header block. This header contains information related to the authentication request that the client may need, such as a list of identity providers acceptable to the service provider, whether the client may interact with the principal through the user interface, and the service provider’s (self-asserted) human-readable name. See Section 4.2.4.2 of [SAML2Prof].

The SOAP envelope MAY contain an SOAP header block (see Section 4.2.4.3 of [SAML2Prof]).

If the client includes the “urn:oasis:names:tc:SAML:protocol:ext:channel-binding” option value in its PAOS header, then the service provider MAY include any number of [ChanBind] SOAP header blocks in the SOAP envelope. Each element MUST contain no content (i.e., be an empty element) and have a distinct Type attribute identifying a type of channel bindings supported by the service provider. If the service provider supports channel bindings via an application layer API that limits its knowledge as to the types supported, then it MUST instead include a single, empty SOAP header block with no Type attribute.

In parallel, the service provider MUST include a corresponding element in the element of its message for each SOAP header block it attaches, containing channel bindings of a particular type. Within each extension element, the Type attribute MAY be set to the channel binding type (if known), and the raw channel binding data MUST be base64-encoded and the result used as the content of the element (per the “default” encoding specified in [ChanBind]). When channel bindings are included, the message MUST be signed via [XMLSig].

If the service provider requires channel bindings, but the client does not support the option, then it MUST instead fail the original request directly. A client MAY require the use of channel bindings by requiring that at least one SOAP header block be returned to it. If the Type is not specified, then it is assumed that the appropriate type to use is known out of band.

If the client includes the “urn:oasis:names:tc:SAML:2.0:cm:holder-of-key” option value in its PAOS header, then the service provider MAY include one or more SOAP header blocks in the SOAP envelope. Each element MUST contain no content and have a distinct Method attribute identifying a type of subject confirmation supported by the service provider. See below for a formal description of this header block.

In the absence of any SOAP header blocks, the client MUST rely on out-of-band knowledge, or assume the use of the “urn:oasis:names:tc:SAML:2.0:cm:bearer” confirmation type (as in the original profile). There is no precendence implied if more than one method is included.

Use of Method values other than “urn:oasis:names:tc:SAML:2.0:cm:bearer” or “urn:oasis:names:tc:SAML:2.0:cm:holder-of-key” are undefined by this profile.

If the client includes the “urn:oasis:names:tc:SAML:2.0:profiles:SSO:ecp:2.0:WantAuthnRequestsSigned” option value in its PAOS header, the service provider MUST digitally sign its request message, or fail the client’s request. The client MUST NOT rely on this behavior, because legacy service provider ECP implementations will not be aware of the option.

If the client includes the “urn:oasis:names:tc:SAML:2.0:conditions:delegation” option value in its PAOS header, or in the presence of other (unspecified) indicators, a service provider MAY request a delegated assertion from the identity provider by including in its request a element containing a element containing a of “urn:oasis:names:tc:SAML:2.0:conditions:delegation”. This is a generic identifier signifying the eventual identity provider as an audience for the assertion, due to the fact that the service provider does not in general know the eventual choice of identity provider to be used. (This identifier is the namespace defined by [SAML2Del], and is reused here for convenience, though the eventual use of delegation may or may not involve that extension.)

The element is a SOAP header block that identifies a method of subject confirmation supported by a service provider, or how an identity provider expects subject confirmation to be performed by the client. It contains the following attributes and elements:

S:mustUnderstand [Required]

The value MUST be “1” (true).

S:actor [Required]

The value MUST be “http://schemas.xmlsoap.org/soap/actor/next”.

Method [Required]

A URI reference that identifies a protocol or mechanism to be used to confirm the subject.

[Optional]

Identifies the subject confirmation data bound into the issued assertion(s) by an identity provider.

The following schema fragment defines the element and its ecp:SubjectConfirmationType complex type:

….

…base64-encoded hash of SP’s SSL cert…

….

The client determines which identity provider is appropriate, possibly influenced by information found in the header block received in the previous step. It is out of scope how the client is provisioned with identity provider information, but SAML V2.0 metadata [SAML2Meta], or a derivative, MAY be used.

It bears noting that the identification of the identity provider, the determination of its location on the network, and the strong verification of its identity in communicating with it (in the following step) are all absolutely critical to the security of this profile and the protection of the user’s credentials. In particular, the use of ordinary commercial web TLS infrastructure (of the form common at the time of this specification’s authoring) do not provide strong guarantees, and sole reliance on that mechanism is discouraged.

2.3.4 ECP Routes to Identity Provider

The client routes the SOAP envelope containing the message on to the selected identity provider, using a modified form of the SAML SOAP binding [SAML2Bind]. Any header blocks received from the service provider MUST be removed.

The SAML request is submitted via the SAML SOAP binding in the usual fashion, but the identity provider MAY respond to the client’s HTTP request with an HTTP response containing, for example, an HTML login form or some other presentation-oriented response. A sequence of HTTP exchanges MAY take place, but ultimately the identity provider MUST complete the SAML SOAP binding exchange and return a SAML response.

However, the use of HTML and a presentation-oriented interface for authentication is NOT RECOMMENDED. Identity providers and clients SHOULD support the use of SOAP- or HTTP-based authentication mechanisms that can be implemented without (or with minimal) user interface support.

If the client supports the use of channel bindings and the service provider requested their use, the client MUST include at least one SOAP header block in the SOAP message to the identity provider, derived from the channel between the client and the service provider. Within each header block, the Type attribute MAY be set to the channel binding type (if known), and the raw channel binding data MUST be base64-encoded and the result used as the content of the element (per the “default” encoding specified in [ChanBind]). The S:actor attribute MUST be set to “http://schemas.xmlsoap.org/soap/actor/next”.

2.3.4.1 “Holder of Key” Subject Confirmation

If the client, service provider, and identity provider all support the use of the “Holder of Key” subject confirmation method (and if it is to be used), then the client MUST demonstrate proof of possession of a key in communicating with the identity provider. This specification does not prescribe the means by which this is done, but for interoperability the following mechanisms are enumerated:

TLS Client Authentication

An enveloped XML Signature over the entire SOAP message (see Section 2.3.11)

Other forms of authentication MAY be used in conjunction with this step; see Section 2.3.5.1 for further discussion.

In the case that an XML Signature or related mechanism is used (in other words, if proof of possession is independent of the transport), the client MAY attach an additional set of SOAP header blocks to the message that carry channel bindings between the client and the identity provider, using the same encoding rules. Such header blocks are distinguished from those representing the client/service provider channel by the absence of the S:actor XML attribute.

Typically this request would be accompanied by some form of HTTP or TLS client authentication.

…base64-encoded hash of SP’s SSL cert…

….

…base64-encoded hash of SP’s SSL cert…

….

At any time during or subsequent to the previous step, the identity provider MUST establish the identity of the principal (unless it returns an error to the service provider). The ForceAuthn attribute, if present with a value of true, obligates the identity provider to freshly establish this identity, rather than relying on an existing session it may have with the principal. Otherwise, and in all other respects, the identity provider may use any means to authenticate the user agent, subject to any requirements included in the message in the form of the element.

2.3.5.1 “Holder of Key” Authentication

If “Holder of Key” subject confirmation is to be used, then the identity provider MAY use TLS client authentication to identify the principal. The identity provider MAY validate the presented X.509 certificate as described in [RFC5280], but this is by no means a requirement.

The key obtained as a result of the TLS handshake, XML Signature, or other mechanism MUST be known to be associated with the principal (see Section 2.4 of [SAML2HOK] in the case that an X.509 certificate is obtained). Precisely how the identity provider satisfies this requirement is out of scope, but of course direct authentication of the principal via an X.509 certificate may offer significant benefits for some deployments.

Failure to demonstrate proof of possession of a key known to be associated with the principal MUST result in an authentication failure.

In the case that TLS Client Authentication is not used but the SOAP message is integrity protected in some other fashion, the identity provider MAY rely on the assistance of any included SOAP header blocks without an S:actor attribute to verify the channel between the client and itself. An identity provider SHOULD insist on verification of channel bindings between itself and the client before accepting a signed message as proof of key possession. If channel bindings are supplied and cannot be verified, then the identity provider MUST fail the authentication.

Regardless of the success or failure of authentication of the principal and of processing the message, the identity provider MUST return a message or SOAP fault. The response is conveyed using the SAML SOAP binding [SAML2Bind], with the message in the body (unless a SOAP fault is signaled).

In the case of “Bearer” subject confirmation, the rules for the response specified in the Browser SSO profile in Section 4.1.4.2 of [SAML2Prof] MUST be followed.

In the case of “Holder of Key” subject confirmation with an X.509 certificate, the rules for the response specified in the Holder of Key Web Browser profile in Section 2.7.3 of [HOKSSO] MUST be followed. If an X.509 certificate is not used, then the same rules MUST be followed, except that the element in the included element is not constrained by [SAML2HOK] and is left to the discretion of the identity provider. Typically a bare key representation is suggested.

If a response is included, the SOAP envelope MUST contain an SOAP header block whose AssertionConsumerServiceURL attribute is set to the location to which the message is to be delivered by the client. The location is derived from the message. See Section 4.2.4.4 of [SAML2Prof].

The SOAP envelope MAY contain an SOAP header block (typically in the case of an unsolicited response).

If the request contains a element containing a element containing a of “urn:oasis:names:tc:SAML:2.0:conditions:delegation”, the identity provider MAY interpret this as a request for issuance of an assertion containing an audience restriction identifying the identity provider itself. This allows for the fact that the service provider may wish to request the ability to present the assertion back to the identity provider as part of a subsequent delegation profile, but may not be able to identify the identity provider by name in advance.

If the identity provider successfully authenticated the message by means of a digital signature, then it SHOULD include an SOAP header block in the SOAP envelope.

The element is a SOAP header block that signals to an interested client that the identity provider authenticated the message by means of a digital signature. It contains the following attributes and elements:

S:mustUnderstand [Optional]

The value can be “1” (true) or “0” (false).

S:actor [Required]

The value MUST be “http://schemas.xmlsoap.org/soap/actor/next”.

The following schema fragment defines the element and its ecp:RequestAuthenticatedType complex type:

2.3.6.2 Verification of Channel Bindings

The identity provider is also responsible for verifying channel bindings supplied by the client and service provider (by comparing them).

The service provider’s channel bindings (if any) are located within elements in the element of the message. If such extensions exist but the message is unsigned, or if the client did not supply at least one matching SOAP header block with the S:actor attribute set to “http://schemas.xmlsoap.org/soap/actor/next”, then the identity provider MUST respond with a message containing an error status.

Additionally, if the service provider does not include any elements in its message, and the client includes a SOAP header block in its message with the S:actor attribute set to “http://schemas.xmlsoap.org/soap/actor/next”, then the identity provider MUST respond with a message containing an error status.

Assuming channel bindings are supplied by both parties, and a match exists, then the identity provider MUST include at least one element in the element of any elements that it returns to the client for delivery to the service provider. It also MUST include the same element(s) as SOAP header blocks in its message to the client. All such elements MAY contain no element content (optionally indicating the type of channel bindings that it verified, if known, or simply acting as an empty signalling element).

Note that the identity provider need not understand or “support” the various types of channel bindings it may encounter in these comparisons. It need only match the Type attributes (if set) and element content via a binary comparison.

2.3.6.3 “Holder of Key” Subject Confirmation

If “Holder of Key” subject confirmation is used, and the response from the identity provider is not an error or fault, then the identity provider MUST include a SOAP header block with a Method of “urn:oasis:names:tc:SAML:2.0:cm:holder-of-key”. The header block MUST contain a element identical to that from the SAML assertion(s) included in the response for the “Holder of Key” confirmation method. That is, it must identify the proof key to be used by the client.

….

….

….

….

2.3.7 ECP Routes Message to Service Provider

The client MUST compare the AssertionConsumerServiceURL attribute from the identity provider’s SOAP header block to the responseConsumerURL attribute found in the SOAP header block sent to the client by the service provider (see Section 2.3.2). This comparison is used for security purposes to confirm the correct response destination. If the values do not match, then the client MUST generate a SOAP fault response to the service provider and MUST NOT return the SAML response it received from the identity provider.

If the client included one or more SOAP header blocks in its request to the identity provider, but no SOAP header blocks are in the response from the identity provider, the client MUST generate a SOAP fault response to the service provider. While a conformant identity provider would generate a SAML error response anyway, the absence of such information could instead indicate that the identity provider did not support the channel bindings extension at all.

Otherwise, the client routes the SOAP envelope containing the message (or SOAP fault) back to the service provider at the location designated by the identity provider’s SOAP header block using the PAOS binding. Any header blocks received from the identity provider MUST be removed first.

The client may need to add and SOAP header blocks to the SOAP Envelope as follows:

The SOAP header block in the response to the service provider is generally used to correlate the response to an earlier request from the service provider. In this profile, the header is not strictly required since the element’s InResponseTo attribute can be used for this purpose, but if the SOAP header block contained a messageID, then a SOAP header block MUST be added, with its refToMessageID attribute set to that value. See Section 10 of [PAOS].

The header block value is typically provided by the service provider to the client with its request, but if the identity provider is producing an unsolicited response (without having received a corresponding SAML request), then it MAY include a header block in its response to the client that indicates, based on mutual agreement with the service provider, how to handle subsequent interactions with the client. This MAY be the URL of a resource at the service provider.

If the service provider included an SOAP header block in its request, or if the identity provider included an SOAP header block in its response, then the client MUST include an identical header block with the response sent to the service provider. The service provider’s value for this header block (if any) MUST take precedence.

2.3.7.1 “Holder of Key” Subject Confirmation

If “Holder of Key” subject confirmation is used, the client MUST demonstrate proof of possession of the key identified by the header block described by Section 2.3.6.3. This specification does not prescribe the means by which this is done, but for interoperability the following mechanisms are enumerated:

TLS Client Authentication

An enveloped XML Signature over the entire SOAP message (see Section 2.3.11)

AGDY854379dskssda

….

….

….

….

Once the service provider has received the SAML response in an HTTP request (in a SOAP Envelope using PAOS), it MUST process the response in accordance with the rules specified by the Browser SSO profile in Sections 4.1.4.3 and 4.1.4.5 of [SAML2Prof]. That is, the same processing rules used when receiving the with the HTTP POST binding generally apply to the use of PAOS.

If “Holder of Key” subject confirmation is used in conjunction with an X.509 certificate, then any such assertion(s) contained in the response MUST be confirmed in accordance with the SAML V2.0 Holder-of-Key Assertion Profile [SAML2HOK], with the confirmation key obtained via the verification of a supported proof mechanism as described by Section 2.3.7.1. If an X.509 certificate is not used, then the service provider MUST verify that the key identified by the element matches the key used by the client, but the exact means are outside the scope of this specification.

In addition, if the service provider included at least one extension in its , any received SHOULD be rejected if it does not contain a corresponding extension in its element.

In the case of an error in processing the response, the service provider MUST return an HTTP error status. Otherwise, it may respond with the service data or other information, or with a redirection to the original request location, or any other valid HTTP response. It MAY rely on cookies [RFC6265] to maintain a session with the client.

The message MUST be signed if the channel bindings extension option is used.

Per the rules specified by the Browser SSO and Holder of Key Browser profiles, the assertions enclosed in the MUST be integrity protected (typically signed) at either the individual assertion or response level.

The delivery of the response in the SOAP envelope via PAOS is essentially analogous to the use of the HTTP POST binding and security countermeasures appropriate to that binding are assumed.

All SOAP headers SHOULD be integrity protected (even in the case of “Bearer” subject confirmation), such as with the use of TLS over every HTTP exchange with the client, though alternative mechanisms MAY be employed.

The service provider SHOULD be authenticated to the client. Server-side TLS authentication may be used, but channel bindings are RECOMMENDED for this purpose, as they can help to address many of the exposures common to commercial TLS infrastructure (assuming the identity provider is trustworthy).

The client MUST authenticate the identity provider during the transmission of the message and prior to the submission of credentials vulnerable to theft. The client SHOULD be authenticated to the identity provider, such as by maintaining an authenticated session. Any HTTP exchanges subsequent to the delivery of the message and before the identity provider returns a MUST be securely associated with the original request.

The assertions issued by the identity provider MAY be encrypted with a key that can be securely associated with the service provider. The key used SHOULD NOT be derived from a TLS certificate believed to belong to the service provider by means of probing endpoints unless that key is otherwise authenticatable and known to be usable for encryption. If a CBC-mode encryption algorithm is used, then it is strongly recommended that the message be digitally signed to address known weaknesses with the use of those algorithms [Enc2011].

If “Holder of Key” subject confirmation is used in conjunction with a message-level proof of possession to the identity provider or service provider such as an XML Signature [XMLSig] instead of a transport-level mechanism like TLS client authentication, then the use of channel bindings is RECOMMENDED. Absent such a mechanism, it is possible for a MITM to replay a signed message obtained from the legitimate client. Replay and freshness checking partially mitigate this threat.

Implementers are also encouraged to review the applicable security and privacy considerations outlined in [HOKSSO] and [SAML2HOK] (presuming that X.509 certificates are used).

The rules specified in the Browser SSO profile in Section 4.1.6 of [SAML2Prof] apply to this profile as well. Specifically, element(s) with a Binding attribute of “urn:oasis:names:tc:SAML:2.0:bindings:PAOS” SHOULD be used to describe the supported location(s) to which an identity provider may send responses to a service provider using this profile.

In addition, elements(s) with a Binding attribute of “urn:oasis:names:tc:SAML:2.0:bindings:SOAP” SHOULD be used to describe the supported location(s) to which a client may relay requests to an identity provider using this profile.

The cb:supportsChannelBindings attribute defined in [ChanBind] SHOULD be added to both types of endpoints to indicate support for channel bindings in conjunction with this profile.

If “Holder of Key” subject confirmation is supported, the metadata usage described in Section 2.8 of [HOKSSO] SHOULD be used in combination with appropriate hoksso:ProtocolBinding values.

An example of a conforming element with “Holder of Key” support is as follows:

Similarly, an example of a conforming element with “Holder of Key” support is as follows:

2.3.11 Message Signing Profile

A simple profile for whole-message signing is provided for use with this specification. If an XML Signature is applied by the client to the SOAP messages in Sections 2.3.4 and/or 2.3.7, then it MUST conform to the following profile:

The element MUST be placed within a SOAP header block.

element MUST be placed within a SOAP header block. The signature’s MUST contain a single with an empty URI attribute (set to “” ) and MUST NOT contain a element.

MUST contain a single with an empty attribute (set to ) and MUST NOT contain a element. The signature MUST NOT contain a element.

element. Since the entire message is being signed (minus the signature itself), any canonicalization method defined for use with [XMLSig] may be used.

An identity provider that conforms to this profile MUST adhere to the relevant normative text in Section 2.3, including the verification of channel bindings and the use of “Holder of Key” subject confirmation. The use of X.509 certificates as a proof mechanism MUST be supported. Other key forms are OPTIONAL.

It MUST support the use of HTTP Basic Authentication, TLS Client Authentication, and the XML Signature mechanism described in section 2.3.4.1.

It MUST also support verification of channel bindings of type “tls-server-end-point” [RFC5929] between itself and the client during authentication via signed message.

A service provider that conforms to this profile MUST adhere to the relevant normative text in Section 2.3, and MUST support the use of channel bindings of type “tls-server-end-point” [RFC5929].

Support for “Holder of Key” subject confirmation is OPTIONAL, but if supported then both TLS Client Authentication and the XML Signature mechanism described in Section 2.3.7.1 MUST be supported as proof of possession mechanisms. The use of X.509 certificates with these mechanisms MUST be supported. Other key forms are OPTIONAL.

An enhanced client or proxy that conforms to this profile MUST adhere to the relevant normative text in Section 2.3, and MUST support HTTP 1.1 [RFC2616] and the use of cookies [RFC6265].

It MUST support the use of channel bindings of type “tls-server-end-point” [RFC5929], both with respect to the service provider and identity provider channels (the latter only if “Holder of Key” via a signature-based authentication mechanism is supported).

It MUST support the use of HTTP Basic Authentication [RFC2617] and TLS Client Authentication to an identity provider.

Support for “Holder of Key” subject confirmation is OPTIONAL.

template-language for tntnet(8)

NAME

ecpp – template-language for tntnet(8)

DESCRIPTION

ecpp is the template-language used by the tntnet-system to generate dynamic content. A template consists of normal content (normally html-data) enriched with special tags, which trigger some special handling. One ecpp-file is compiled into a C++-class. The C++-class is placed into the namespace component. A ecpp-file compiled into a C++-class is called component. The name of the class is the basename of the file. request, reply, qparam Each component has 3 parameters: request, reply and qparam. request holds information about the client-request like http headers and the url, but also additional parameters specified in the config-file tntnet.xml(7). The type of request is tnt::HttpRequest. reply receives the answer from the component. The component can set additional http-headers here, set cookies and – most important – generate output. The most important methods here are reply.out() and reply.sout(). Both return a std::ostream, which receives the output of the component. reply.sout() has a filter installed, which translates some characters, whith special meanings in html to the corresponding html-entities. The characters are <, >, &, ” and ‘. This is useful for printing values from variables to the html-code. qparam holds the query-parameters parsed from GET- or POST-parameters or received from other components. The type of qparam is tnt::query_params. Normally you use a <%args>-block to specify the parameters, but there are special cases, where it is useful to access these directly. component adressing Each component has a unique name. The name is composed from the class-name, the character ‘@’ and the name of the shared library, it is located. Components can have internal subcomponents. The name of the internal subcomponent is appended to the classname separated by a dot (.). special rule for line feeds after a -tag A line feed immediately after a closing tag for all <%something>-blocks are ignored. Hence blocks followed immediately one after another does not generate white space in output, which is often undesirable. error-handling Error-handling is done by exception. Tntnet catches all exceptions thrown by components and handles them properly. Exceptions must be derived from std::exception. Exceptions derived from tnt::HttpError, are handled separately. They carry a http-return-code, which is sent to the client. Other exceptions derived from std::exception, result in a http error code 500 (Internal Server Error).

TAGS

<$ expr $> Print expressions expr to the outputstream. The characters <, >, &, ” and ‘, which have special meanings in html, are translated to the corresponding html-entities. <$$ expr $> Print expressions expr without translating characters with special meaning in html to html entities to the output stream. Conditional output. Print expression expr to the outputstream, if cond evaluates to true. Characters with special meaning in html are translated to the corresponding html-entities. Conditional output. Print expression expr to the outputstream, if cond evaluates to true. Characters with special meaning in html are not translated to the corresponding html-entities. <& component [ arguments ] > Call the specified component. The output of the component is printed into the outputstream. If the component-name does not start with a letter, the ecpp-compiler treats it as a expression, which returns the name of the component. You must surround the expression in brackets, if it contains spaces. The arguments-part specify the parameters, the component will receive. Arguments are name-value-pairs separated by ‘=’. They are put in the qparam-parameter of the component and are normally declared in the <%args>-block. Values can be specified in 3 forms: As a plain word without spaces As a string enclosed in quotation marks As a expression enclosed in brackets A single plain word in the argumentlist is treated as a variable of type cxxtools::query_params and a copy is passed to the component. Other parameters are added to this copy. If you want to pass all parameters of the current component put the variable qparam as a plain word in the argument list. Closing-tag for a component-call. When components are called, this closing-tag might occur later. The code in <%close>-block is placed here. <{...}> C++-inline-processing-block. The code in this block is copied into the C++-class unchanged. A linefeed after the closing tag is not ignored. <#...#> Comment-block. Everything in this block is ignored. <%application [ scope="component|page|global" ] >… Variables defined here, have the lifetime of the application. Application-scope is automatically locked. <%args>… Defines GET- or POST-parameters recieved by the component. Each argument has a name and optionally a defaul-value. The default-value is delimited by ‘=’ from the name. A single argument-definition followed by a semicolon (;). In the component a variable with the same name of type std::string is defined, which receives the value. A argument-name can be prefixed by a type-definition. The ecpp-compiler generates code, which tries to convert the value with the input-stream-operator. This means, that each type, which can be read from a input-stream (std::istream) can be used. If the argument can’t be converted, a exception is thrown. Argumentnames can be postfixed by empty square-brackets. This defines a std::vector with the specified type or std::string, if no type is specified. This way multiple values with the same name can be received. If a type is specified, each value is converted to the target-type. <%close>… Code in these tags is placed into the calling component, when a closing tag is found. The <%close> receives the same parameters like the corresponding normal component call. <%config>… Often webapplications need some configuration like database-names or login-information to the database. These configuratioin-variables can be read from the tntnet.xml. Variablenames ended with a semicolon are defined as static std::string-variables and filled from tntnet.xml. A variable can be prepended by a type. The value from tntnet.xml is then converted with a std::istream. You can also specify a default value by appending a ‘=’ and the value to the variable. Example: <%config> dburl = “sqlite:db=mydbfile.sqlite”; int maxvalue = 10; tntnet.xml: postgresql:dbname=mydb <%cpp>… C++-processing-block. The code between these tags are copied into the C++-class unchanged. A linefeed after the closing tag is ignored. <%def name>… Defines a internal subcomponent with the name name, which can be called like other components. <%doc>… Comment-block. Everything in this block is ignored. A linefeed after the closing tag is ignored. <%get>… Works like a <%args> block but receives only GET parameters. <%i18n>… Encloses a block of text-data, which is to be translated. See ecppl(1) and ecppll(1) for details. <%include>filename The specified file is read and compiled. <%param>… Defines parameter received from calling components. In contrast to query-parameters these variables can be of any type. The syntax (and the underlying technology) is the same like in scoped variables. See the description about scoped variables to see how to define parameters. The main difference is, that a parameter variable has no scope, since the parameter is always local to the component. <%out> expr Same as <$$ ... $>. Prints the contained C++ expression expr. <%post>… Works like a <%args> block but receives only POST parameters. <%pre>… Defines C++-code, which is placed outside the C++-class and outside the namespace-definition. This is a good place to define #include-directives. <%request [ scope="component|page|global" ] >… Define request-scope variables. Variables defined here, has the lifetime of the request. <%session [ scope="component|page|global" ] >… Variables defined here, has the lifetime of the session. Sessions are identified with cookies. If a <%session>-block is defined somewhere in a component, a session-cookie is sent to the client. Sessions are automatically locked. <%securesession [ scope="component|page|global" ] >… Secure session is just like session but a secure cookie is used to identify the session. Secure cookies are transfered only over a ssl connection from the browser and hence the variables are only kept in a ssl secured application. If a variable defined here is used in a non ssl page, the variable values are lost after the current request. <%sout> expr Same as <$ ... $>. Prints the contained C++ expression expr. The characters <, >, &, ” and ‘, which have special meanings in html, are translated to the corresponding html-entities. <%thread [ scope="component|page|global" ] >… Variables defined here, has the lifetime of the thread. Each thread has his own instance of these variables. Thread-scope-variables do not need to be locked at all, because they are only valid in the current thread.

SCOPED VARIABLES

Scoped variables are c++-variables, whose lifetime is handled by tntnet. These variables has a lifetime and a scope. The lifetime is defined by the tag, used to declare the variable and the scope is passed as a parameter to the tag. There are 5 different lifetimes for scoped variables: request The variable is valid in the current request. The tag is <%request>. application The variable is valid in the application. The tag is <%application>. The application is specified by the shared-library of the top-level component. session The variable is valid for the current session. The tag is <%session>. If at least session-variable is declared in the current request, a session-cookie is sent to the client. thread The variable is valid in the current thread. The tag is <%thread>. param The variable receives parameters. The tag is <%param>. And 3 scopes: component The variable is only valid in the same component. This is the default scope. page The variable is shared between the components in a single ecpp-file. You can specify multiple internal subcomponents in a %def-block. Variables, defined in page-scope are shared between these subcomponents. global Variables are shared between all components. If you define the same variable with global-scope in different components, they must have the same type. This is achieved most easily defining them in a separate file and include them with a <%include>-block. Variables are automatically locked as needed. If you use session-variables, tntnet ensures, that all requests of the same session are serialized. If you use application-variables, tntnet serializes all requests to the same application-scope. Request- and thread-scope variables do not need to be locked at all, because they are not shared between threads. Syntax of scoped variables Scoped variables are declared with exactly the same syntax as normal variables in c++-code. They can be of any type and are instantiated, when needed. Objects, which do not have default constructors, need to be specified with proper constructor-parameters in brackets or separated by ‘=’. The parameters are only used, if the variable need to be instantiated. This means, that parameters to e.g. application-scope variables are only used once. When the same component is called later in the same or another request, the parameters are not used any more. Examples Specify a application-specific global variable, which is initialized with 0: <%application> unsigned count = 0; Specify a variable with a user-defined type, which holds the state of the session: <%session> MyClass sessionState; Specify a persistent databaseconnection, which is initialized, when first needed and hold for the lifetime of the current thread. This variable may be used in other components: <%thread scope="global"> tntdb::Connection conn(dburl);
