In order to provide roaming services, it is necessary to have a
standardized method for identifying users.  This document defines the
syntax for the Network Access Identifier (NAI), the user identity
submitted by the client during network authentication.  "Roaming" may
be loosely defined as the ability to use any one of multiple Internet
Service Providers (ISPs), while maintaining a formal,
\%customer-vendor
relationship with only one.  Examples of where roaming capabilities
might be required include ISP "confederations" and \%ISP-provided
corporate network access support.  This document is a revised version
of RFC 2486, which originally defined NAIs.  Enhancements include
international character set and privacy support, as well as a number
of corrections to the original RFC.

This document is a product of the RADIUS EXTensions Working Group of
the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
