Thread:Project:Support desk/LoginAuthenticateAudit hook return from invalid user

I have implemented the Fail2ban extension which uses the hook LoginAuthenticateAudit In its base function it works like a champ however I am looking to augment the function by including output from the hook when a user is entered that is not present in the database.

As of now:
 * When logging into the wiki using a known user you get the expected return
 * When logging into the wiki using an unknown user you do not get any return

My Question:
 * Is there a way so determine a bad login attempt using an unknown user through the hook LoginAuthenticateAudit?
