14.2.2 Auth Phase Fast Path

Assume that client wants to log in as user U and that user account uses authentication method M. The fast authentication path is used if both client and server used method M to generate authentication data in the initial handshake. In that case the first round of authentication has been already commenced during the handshake. Now, dependign on the authentication method, further authentication data can be exchanged until server either refuses or accepts connection.
