                           The XAuth Protocol
                     draft-hardt-xauth-protocol-02

Abstract

   Client software often desires resources or identity claims that are
   independent of the client.  This protocol allows a user and/or
   resource owner to delegate resource authorization and/or release of
   identity claims to a server.  Client software can then request access
   to resources and/or identity claims by calling the server.  The
   server acquires consent and authorization from the user and/or
   resource owner if required, and then returns to the client software
   the authorization and identity claims that were approved.  This
   protocol can be extended to support alternative authorizations,
   claims, interactions, and client authentication mechanisms.
