Hmm, where is 'Domain Users' and the groups are (rightly) being mapped
to the '*' domain.

Does 'Domain Users' have a 'gidNumber' attribute containing a number
inside the '10000-999999' range ?
Do your users have a 'uidNumber' attribute containing a unique number
inside the same range ?

What version of Samba are you using ?
If it is less than 4.6.0 then you also need this line:

winbind nss info = rfc2307

>From 4.6.0 it is replaced by:

idmap config TESTDOM : unix_nss_info
