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