I'm concerned that the current "alv" and "min_alv" text wouldn't survive IESG review since depending up NIST SP-800-63-2 is US-centric. The point of OpenID Connect "acr" (authentication context class reference) claim using RFC6711 is that the authentication context values used are internationalized.
I agree that using the strings "1", "2", "3", and "4" to refer to the ISO 29115 authentication level values would be preferable to the current "alv" text, since that approach is much more likely to survive IESG review and result in an approved RFC. I'd therefore suggest making this change sooner rather than later. -- Mike From: oauth-boun...@ietf.org [mailto:oauth-boun...@ietf.org] On Behalf Of Phil Hunt Sent: Tuesday, August 27, 2013 4:37 PM To: John Bradley Cc: oauth@ietf.org WG Subject: Re: [OAUTH-WG] Fwd: New Version Notification for draft-hunt-oauth-v2-user-a4c-01.txt See below.

We need to talk about what you have done with "min_alv" vs "acr" from connect which is extensible via a IANA registry of Authentication contexts. If it came down to reserving the strings 1 2 3 4 for the ISO29115 reference that could probably be arranged. I don't know that throwing an error if the min can't be supported is the correct thing. We had a lot of debate about that and decided that returning the actual acr and letting the client decide was better than an error. [PH[ I agree. Also remember that the request is not signed so someone could modify it to remove min_alv and spoof a RP that expects all positive results to meet what it asked for. More discussion on min_alv is required. [PH] Yes. Returning what actually was done without an error is a better approach. Also, just noticed that the "hint" parameter should be "login_hint". I think we also need to discuss how the client detects the profile API type and whether the AS can return multiple endpoints (and is that even a good thing). A structured attribute giving endpoint type and URL might be the way to go. John B. On 2013-08-27, at 12:52 PM, Phil Hunt <phil.h...@oracle.com<mailto:phil.h...@oracle.com>> wrote: FYI. Based on feedback from Berlin, Tony and I have revised the draft to include: * Alignment with OpenID Connect (using id_token) * Always returns a JWT * Minimum assertion level on request * Return information about the type of authentication performed Thanks for your input.
