default domain for winbind

[Ondrej Valousek]

Question:
In multi-domain environment, domain has to be specified when querying 
winbind. Example:

[root at dorado_v1 samba]# wbinfo -i "PRAGUE\ondrejv"
PRAGUE\ondrejv:*:14019:10000:Ondrej Valousek:/home/ondrejv:/bin/tcsh

.. this works OK, but this:

[root at dorado_v1 samba]# wbinfo -i ondrejv
Could not get info for user ondrejv

.. does not. My question - is it possible to define a default domain for 
winbind if none is specified? I would expect "workgroup" parameter in 
smb.conf could be used, but obviously it is not.

Thanks,
Ondrej
