Subject: [security-services] Action A11: XML Signature requirements for SOAPProfile
The SOAP profile in the bindings-06 draft specifies that all SOAP messages which include SAML assertions must be signed. The current signature requirements are too restrictive; in particular, they are not compatible with SOAP header elements that have "actor" attributes. I propose that we change lines 828-829 and 978-979 (.pdf version) to read: The <dsig:Signature> element MUST apply to all the SAML assertion elements in the SOAP <Header>, and all the relevant portions of the SOAP <Body>, as required by the application. Specific applications may require that the signature also apply to additional elements. The wording is a bit clumsy; feel free to fix it if you want. (Do we need to say anything about whether the receiver should rely on unsigned portions of the SOAP message? My first inclination is that it's up to the application, so we shouldn't say anything. Perhaps we need something in security considerations?) - irving - ----------------------------------------------------------------------------------------------------------------- The information contained in this message is confidential and is intended for the addressee(s) only.
