/**
* A simple server login module useful to quick setup of security for testing
* purposes. It implements the following simple algorithm:
* <ul>
* <li> if password is null, authenticate the user and assign an identity of "guest"
* and a role of "guest".
* <li> else if password is equal to the user name, assign an identity equal to
* the username and both "user" and "guest" roles
* <li> else authentication fails.
* </ul>
