message flow of OAuth 2.0 [RFC6749]. As indicated in the figure, this document impacts the exchange of messages (E) and (F) since SASL is used for interaction between the client and the resource server instead of HTTP.

   A Set of Simple Authentication and Security Layer (SASL) Mechanisms                                for OAuth


   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 server.  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.
