Subject: [security-services] FW: [security-bindings] Multiple authn assertionsin one Browser Artifact Profile exchange?
-----Original Message----- From: Irving Reid To: 'security-bindings@lists.oasis-open.org' Cc: Tahura Chaudhry Sent: 11/19/01 7:11 PM Subject: [security-bindings] Multiple authn assertions in one Browser Artifact Profile exchang e? In the browser artifact profile as described in the bindings-06 document (http://lists.oasis-open.org/archives/security-services/200111/msg00020. html , section 4.1.5), lines 565-567 imply that more than one authentication assertion could be transferred. This raises all sorts of questions about how the receiver should behave, particularly if the authn assertions refer to different subjects. Do we want to say anything more about this? Alternatives include: (a) Make no changes to the spec. Implementers are free to choose whatever behaviour they think is appropriate for their solution. (b) Specify that all authn assertions must contain the same Subject (or at least, the same NameIdentifier within the Subject) (c) Specify exactly how the receiver should behave. Two possibilities are to say that access should be allowed if any one of the Subjects would be allowed, or that access should only be allowed if all of the Subjects are allowed. My life would be easiest if we choose (b), though I could see how it might be too severe a constraint on some applications. - irving - ------------------------------------------------------------------------ ----------------------------------------- The information contained in this message is confidential and is intended for the addressee(s) only.
