The IESG has approved the following document: - 'A set of SASL Mechanisms for OAuth' (draft-ietf-kitten-sasl-oauth-23.txt) as Proposed Standard This document is the product of the Common Authentication Technology Next Generation Working Group. The IESG contact persons are Stephen Farrell and Kathleen Moriarty. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-kitten-sasl-oauth/ Technical Summary OAuth enables a third-party application to obtain limited access to a protected resource, either on behalf of a resource owner by orchestrating an approval interaction, or by allowing the third-party application to obtain access on its own behalf. This document defines how an application client uses credentials obtained via OAuth over the Simple Authentication and Security Layer (SASL) to access a protected resource at a resource serve. Thereby, it enables schemes defined within the OAuth framework for non-HTTP- based application protocols. Clients typically store the user's long-term credential. This does, however, lead to significant security vulnerabilities, for example, when such a credential leaks. A significant benefit of OAuth for usage in those clients is that the password is replaced by a shared secret with higher entropy, i.e., the token. Tokens typically provide limited access rights and can be managed and revoked separately from the user's long-term password. Working Group Summary The review process for this document was very long and complicated. See the shepherd write-up for details, it is comprehensive and... ...long... but ends with: The fourth WGLC achieved consensus with support from both kitten and the oauth working groups. It did result in a few clarifications to the document, fixing the ABNF and examples, noting the generic SASL cancellation token functionality, and reiterating the TLS requirements for using this mechanism, but these changes were not controversial. Document Quality The long gestation period here has resulted in pretty high quality documentation of this not that hard to understand combination of schemes. I'm not sure about implementation status. Personnel The document shepherd is Benjamin Kaduk. The responsible Area Director is Stephen Farrell.
