authusername converts between an authentication username and a Horde  
username (meaning the username Horde is using internally).  Key in  
that statement: it doesn't change the authentication username.

If the original authentication username isn't valid for your  
authentication backend (i.e. an IMAP server), this doesn't work.

You probably want the preauthenticate hook instead.
