samba - Aug 2003 - Question on 'winbind use default domain = yes'

After setting winbind use default domain = yes in smb.conf,

Does this mean If use the "Enterprise Admins" in a write list, 

I specify as write list = @"Enterprise Admins"   

OR

write list = @DOMAIN+"Enterprise Admins"  ?

Also I would like to more about using "+" as my seperator.  

Does this require my Windows users who access smb shares to use DOMAIN+user
or should they be able to use Windows's default DOMAIN\user ?

Thanks,

Aaron Colichia
