Have a very large customer (26000+ users) needing to set up a very 
limited form of file sharing using samba.  Stability is the major issue 
here and there's not that much complexity needed in regard to 
permissions.  This is also being configured in a failover environment.  
So, winbind is not really an option....to make things more interesting 
many of the domain accounts begin with ~'s and #'s so creating matching 
system accounts would be a bit of a headache.  The easiest and most 
stable solution was just to map all the users to respective accounts.
