LoginModule

public class SampleLoginModule
extends Object
implements LoginModule

This sample LoginModule authenticates users with a password.

This LoginModule only recognizes one user: testUser

testUser's password is: testPassword

If testUser successfully authenticates itself, a SamplePrincipal with the testUser's user name is added to the Subject.

This LoginModule recognizes the debug option. If set to true in the login Configuration, debug messages will be output to the output stream, System.out.
