[Samba] Winbind Help : NT Group permissions don't seem to apply when us ing username map

[Wieprecht, Karen M.]

Samba 2.2.5 
security = domain with winbind 
Also Using a username map for users with a corresponding UNIX account. 

Username.map:

Karen = WALNETNT_karen  
(unix)	(nt)

Causes karen to come onto the samba share with UID and GID matching that
used on the UNIX side. 

This lets karen (nt) write in any areas owned by karen (UNIX),  but public
areas that are shared to all Domain Users (write list = @"WALNETNT_Domain
Users")  are not writable now by karen from the NT side.   It seems that
once the UNIX UID is assigned,  the daemons lose all information about any
domain group memberships that the user had.  


Any idea how I can fix this?  

	Thanks,
