  Generic Security Service Application Programming Interface (GSS-API)
                           Naming Extensions

Abstract

   The Generic Security Service Application Programming Interface
   (GSS-API) provides a simple naming architecture that supports name-
   based authorization.  This document introduces new APIs that extend
   the GSS-API naming model to support name attribute transfer between
   GSS-API peers.
