   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 OAuth over the
   Simple Authentication and Security Layer (SASL) or the Generic
   Security Service Application Program Interface (GSS-API) to access a
   protected resource at a resource serve, and additionally defines
   authorization and token issuing endpoint discovery.  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 token.
   Tokens typically provided limited access rights and can be managed
   and revoked separately from the user's long-term credential
   (password).
