I think we need management APIs now to manage the new endpoint, but seriously this introspection proposal has privacy issues, to avoid these I would encrypt the tokens and then this would be a useless endpoint, also this has issues with symmetric POP tokens, but maybe this was only designed to work on bearer tokens.

That sounds like an awesome idea! Very useful for a variety of use cases that people have already mentioned on that list. Maybe that service should respond in JSON with, say, { "active": true } if it's still valid. That's a great start, and that should obviously be MTI. But while we're there, we probably want to know what else the token is for, since this service will probably know that, so let's add in the "scope" and "client_id" and whatever other meta-information we have about the token. If this endpoint doesn't have that information? Well then, I guess it can't return it. So we need to make sure to be flexible about that while we define a common core set of semantics. Flexibility like that is very powerful and could be used in a variety of protocols and deployments across domains and vendors. You know, this idea is sounding better and better. In fact, I'll do you one better. I think this is such a fantastic idea that I wrote it all down in RFC format: http://tools.ietf.org/html/draft-richer-oauth-introspection-06 Glad to have you on board, Phil. -- Justin On 7/29/2014 9:02 PM, Phil Hunt wrote: I think one alternative to an introspection service is a revocation status service. But it is often not needed if token lifetimes are small (minutes / session life) compared to the refresh token which might last much longer. Again having info on the case helps explain the requirements of your case and we can tell what the best pattern is.

I realize that might or might not be practical in some cases, but I haven’t heard that alternative discussed, so I thought I’d bring it up. I also second Phil’s comment that it would be good to understand the use cases that this is intended to solve before embarking on a particular solution path. -- Mike From: OAuth [mailto:oauth-boun...@ietf.org<mailto:oauth-boun...@ietf.org>] On Behalf Of George Fletcher Sent: Tuesday, July 29, 2014 3:25 PM To: Phil Hunt; Thomas Broyer Cc: oauth@ietf.org<mailto:oauth@ietf.org> Subject: Re: [OAUTH-WG] Confirmation: Call for Adoption of "OAuth Token Introspection" as an OAuth Working Group Item We also have a use case where the AS is provided by a partner and the RS is provided by AOL. Being able to have a standardized way of validating and getting data about the token from the AS would make our implementation much simpler as we can use the same mechanism for all Authorization Servers and not have to implement one off solutions for each AS.

Or may this be only of interest to specific protocols like UMA? From a technique principle, the draft is important and sound. I am just not there yet on the reasons for an interoperable standard.
