I’m happy to report that a substantially revised OAuth 2.0 Token Exchange draft has been published that enables a broad range of use cases, while still remaining as simple as possible. This draft unifies the approaches taken in the previous working group draft and draft-campbell-oauth-sts, incorporating working group input from the in-person discussions in Prague and mailing list discussions. Thanks to all for your interest in and contributions to OAuth Token Exchange! Brian Campbell deserves special recognition for doing much of the editing heavy lifting for this draft.
The core functionality remains token type independent. That said, new claims are also defined to enable representation of delegation actors in JSON Web Tokens (JWTs). Equivalent claims could be defined for other token types by other specifications.
See the Document History section for a summary of the changes made. Please check it out!
