Network Access Identifier (NAI)


The Network Access Identifier (NAI) is the user identity submitted by the client during network access authentication. The NAI is used when roaming, to identify the user as well as to assist in the routing of the authentication request to the user's authentication server.

The NAI does not necessarily have to be the same as the user's e-mail address or the user identity submitted in an authentication for an application.

The NAI is defined in RFC 4282.
