A mechanism for seeking access of a client to a first server is described.
The mechanism involves determining that a client seeking access to the
first server is not authenticated by an authentication server. The
mechanism further involves communicating a request for login information
to be returned to the second server from the client. Login information is
received at the authentication server from the client. The client is
authenticated by comparing the login information with authentication
information maintained by the authentication server. When the login
information matches the authentication information, a user authentication
indicator is generated at the authentication server and the user sends
the authentication indicator to the first server.
