It is best to actually end up using one authentication db, IMHO. But you 
should be able to solve your problem by:

1)Upgrading samba-2.2.4
2)Setting "winbind use default domain = yes" in the global section of 

Now, winbind users for the domain specified in the "workgroup = " 
parameter will not get the winbind or winbind seperator prepended to 
their usernam.
