user authentication

Authentication is used to verify that the user is allowed access to the server by virtue of having been added to the membership database by the administrator of the server. Only users that are part of the membership database are permitted to join the session. User authentication should not be confused with password protection of a session. A password can be added to a session so that only those members who know the password can join a particular session. Authentication requires a server that supports authentication, while any computer can put a password on a session.
