These drafts address the issues discussed on the calls and in the issue tracker. The changelogs can be viewed at these URLs:

Note that the Back-Channel Logout spec is compatible with the working group SecEvent spec https://tools.ietf.org/html/draft-ietf-secevent-token-00.

This note starts a one-week review period of these specifications by the working group. If blocking issues aren’t raised within a week, we will proceed with the formal review period preceding an OpenID Foundation Implementer’s Draft adoption vote.

OAuth Authorization Server Metadata decoupled from OAuth Protected Resource Metadata

By

On January 19, 2017

In Claims, JSON, OAuth, Specifications

OAuth logoThe IETF OAuth working group decided at IETF 97 to proceed with standardizing the OAuth Authorization Server Metadata specification, which is already in widespread use, and to stop work on the OAuth Protected Resource Metadata specification, which is more speculative. Accordingly, a new version of the AS Metadata spec has been published that removes its dependencies upon the Resource Metadata spec. In particular, the “protected_resources” AS Metadata element has been removed. Its definition has been moved to the Resource Metadata spec for archival purposes. Note that the Resource Metadata specification authors intend to let it expire unless the working group decides to resume work on it at some point in the future.
