+===== Introduction =====
+This document is one of a series of three documents under
+consideration by the AAAarch RG dealing with the authorization
+requirements for AAA protocols.  The three documents are:
+  * AAA Authorization Framework (this document)
+  * AAA Authorization Requirements
+  * AAA Authorization Application Examples
+There is a demonstrated need for a common scheme which covers all
+Internet services which offer Authorization.  This common scheme will
+address various functional architectures which meet the requirements
+of basic services.  We attempt to describe these architectures and
+functions as a basis for deriving requirements for an authorization
+protocol.
+These architectures include Policy structures, Certificate
+Authorities, Resource Managers, Inter-Domain and Multi-Domain
+schemes, and Distributed Services.  The requirements are for the
+expected use of Authorization services across these architectures.
+A representative set of applications that may use this architecture
+to support their authorization needs is presented in [3].  The
+examples in [3] show how this framework may be used to meet a wide
+variety of different authorization needs.
+We expect that this work may be extended in the future to a more
+comprehensive model and that the scheme described here will be
+incorporated into a framework that includes authentication,
+accounting and auditing.  We have referenced a number of
+authorization sources, but also recognize that there may be some that
+we have missed and that should be included.  Please notify one of the
+authors of any such oversight so it can be corrected in a future
+revision.
+In general, it is assumed that the parties who are participating in
+the authorization process have already gone through an authentication
+phase.  The authentication method used by those parties is outside
+the scope of this document except to the extent that it influences
+the requirements found in a subsequent authorization process.
+Likewise, accounting requirements are outside the scope of this
+document other than recording accounting data or establishing trust
+relationships during an authorization that will facilitate a
+subsequent accounting phase.
+The work for this memo was done by a group that originally was the
+Authorization subgroup of the AAA Working Group of the IETF.  When
+the charter of the AAA working group was changed to focus on MobileIP
+and NAS requirements, the AAAarch Research Group was chartered within
+the IRTF to continue and expand the architectural work started by the
+Authorization subgroup.  This memo is one of four which were created
+by the subgroup.  This memo is a starting point for further work
+within the AAAarch Research Group.  It is still a work in progress
+and is published so that the work will be available for the AAAarch
+subgroup and others working in this area, not as a definitive
+description of architecture or requirements.
