[Samba] samba upgrade

[Norman Zhang]

Hi,

LM 9.0 (samba 2.2.6) can setup to authenticate using winbind. When I do
wbinfo -u, only
users of my NT domain is listed,

e.g.,
user_a
user_b
...

Now I upgrade to 2.2.7 using Mandrake update, and wbinfo -u, I see

e.g.,
MYDOMAIN\user_a
MYDOMAIN\user_b
...

Which option in smb.conf can I suppress the printing of MYDOMAIN?

Regards,
Norman
