That's fair, John. Having a mandatory-to-implement mechanism in place is certainly useful. Pushing stronger security mechanisms to other specifications is also fine. It would be good to re-read the document to see whether we can actually fit the currently worked on security mechanisms into the spec at a later stage or whether there are some problems with the extensibility story.
Ciao Hannes From: ext John Bradley [mailto:ve7...@ve7jtb.com] Sent: Thursday, June 06, 2013 11:54 AM To: Tschofenig, Hannes (NSN - FI/Espoo) Cc: ext Tim Bray; Manger, James H; oauth@ietf.org Subject: Re: [OAUTH-WG] draft-ietf-oauth-dyn-reg and bearer tokens There are a couple of reasons. One criticism Hannes and others make of OAuth specs is they are not tightly profiled enough to be interoperable without further out of band configuration and profiling. Making registration work with minimal ambiguity was a priority for Connect and that has carried over. I am not opposed to having this extended at some point in the future, once we have a second token type. The new token type should be available to do updates as well. The problem is that starting down the HoK route potentially requires a registered client that may need to be registered to do the registration. I think that is best left to another spec to sort out the possible turtles. So the default needs to be bearer tokens unless registration is extended by another profile. John B.

If we want to support stronger security mechanisms (which the group has decided to work on already) then we need to have a story on how to support the other mechanisms as well . _______________________________________________ OAuth mailing list OAuth@ietf.org<mailto:OAuth@ietf.org> https://www.ietf.org/mailman/listinfo/oauth
