\subsubsection{Login - First Method}
The first method of login is done by the `login(name, hashedPass,
isExpirable)'. This message is sent to the worker server from a client. Then it
is routed back to the master server. The master server approves/disapprove the
login attempt and returns back the return codes (ref ...). The return code is
routed back to the client. The following is a diagram of an example login
request.
