Using Password Authentication Protocol (PAP) for MAC Authentication

The Password Authentication Protocol (PAP) provides a simple method for the peer to establish its identity. PAP is considered a weak authentication method as the password details of the client are sent over to the authentication server using a one-way hash function, which is prone to repeated trail attacks. Password of the client is appended with the authentication servers secret password and a hash output is generated. This data is sent over a RADIUS packet to the authentication server.
