Technical Summary
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.
