                    Name Attributes for the GSS-API
           Extensible Authentication Protocol (EAP) Mechanism

Abstract

   The naming extensions to the Generic Security Service Application
   Programming Interface (GSS-API) provide a mechanism for applications
   to discover authorization and personalization information associated
   with GSS-API names.  The Extensible Authentication Protocol GSS-API
   mechanism allows an Authentication, Authorization, and Accounting
   (AAA) peer to provide authorization attributes alongside an
   authentication response.  It also supplies mechanisms to process
   Security Assertion Markup Language (SAML) messages provided in the
   AAA response.  This document describes how to use the Naming
   Extensions API to access that information.

1.  Introduction

   The naming extensions [RFC6680] to the Generic Security Service
   Application Programming Interface (GSS-API) [RFC2743] provide a
   mechanism for applications to discover authorization and
   personalization information associated with GSS-API names.  The
   Extensible Authentication Protocol GSS-API mechanism [RFC7055] allows
   an Authentication, Authorization, and Accounting (AAA) peer to
   provide authorization attributes alongside an authentication
   response.  It also supplies mechanisms to process Security Assertion
   Markup Language (SAML) messages provided in the AAA response.  Other
   mechanisms such as SAML Enhanced Client (EC) [SASL-SAML] also support
   SAML assertions and attributes carried in the GSS-API.  This document
   describes how to use the Naming Extensions API to access that
   information.
