Description

Request to expand the CXF STSClient to support a configuration option that enables an X509Certificate to be used as the saml:SubjectConfirmation KeyInfo element when making a WS-Trust RequestSecurityToken request.

Rationale is as follows:

1. The SAML 1.1 specification is flexible with regard to the type of XMLSignature KeyInfo (ds:KeyInfo) that may provided in a saml:SubjectConfirmation element to support the holder-of-key confirmation method.

2. Some relying parties require an X509 Certificate to be provided in the assertion confirmation data in order to perfom validation. For example, any relying party that uses WSS4J version 1.5.8 or earlier for SAML assertion validation (with holder-of-key conf) requires the X509 Certificate to exist in the subject confirmation data.

3. Accordingly, some STS implementations allow RequestSecurityToken ds:KeyInfo element to optionally contain either a ds:X509Certificate or the corresponding ds:KeyValue for the public key within the RequestSecurityToken message.
