Abstract

   This memo describes several examples of applications requiring
   authorization.  Each application is described in terms of a
   consistent framework, and specific authorization requirements of each
   application are given.  This material was not contributed by the
   working groups responsible for the applications and should not be
   considered prescriptive for how the applications will meet their
   authorization needs.  Rather the intent is to explore the fundamental
   needs of a variety of different applications with the view of
   compiling a set of requirements that an authorization protocol will
   need to meet in order to be generally useful.
