Abstract

   In order to provide inter-domain authentication services, it is
   necessary to have a standardized method that domains can use to
   identify each others users.  This document defines the syntax for the
   Network Access Identifier (NAI), the user identity submitted by the
   client prior to accessing network resources. This document is a
   revised version of RFC 4282 [RFC4282], which addresses issues with
   international character sets, as well as a number of other
   corrections to the previous document.

Status of this Memo

   This Internet-Draft is submitted to IETF in full conformance with the
