Agreed.  And (unlikely scenario, but...) what can you do if you want  
to auth as another user?  You will never get the chance.  Also the  
fact you don't even know what user you are preauth'd as.

Wondering if it makes sense for our library to reject PREAUTH by  
default due to some of these issues.
