Network Access Identifier

The acronym NAI is an abbreviation for Network Access Identifier ( German  network access identifier ). In computer networks , the network access identifier is a standard method of identifying users who request access to a network. The standard syntax is "user @ realm". It is mainly used for two purposes:

• The NAI is used when roaming to identify the user.
• Assistance in forwarding the authentication request to the user's authentication server .

NAIs were originally defined in RFC 2486 , which was replaced by RFC 4282 , which in turn was replaced by RFC 7542 . The latter RFC ( Request for Comments ) is the current standard for the NAI. NAIs are often found as user IDs in the RADIUS ( Remote Authentication Dial-In User Service ) and Diameter network access protocols and the EAP ( Extensible Authentication Protocol ) authentication protocol .

The NAI does not necessarily have to match the user 's email address or the user's IP that is transmitted in an authentication for an application.
