What Conch does for this is takes whatever error 
the authentication raises, whether it be invalid 
user, invalid password, etc., and turns it into a 
generic 'not authenticated' message.  If you want 
to keep attackers from knowing which names are 
actual users, you probably just want to do that, 
rather than having a flag in the Authorizer.
