The Network Access Identifier
draft-ietf-radext-nai-01
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.
