[Samba] Issues post AD migration

Hi Rowland,
The issue seems to be due to the groups who decided not to show up in AD. Strangely, even when we added the group with the same name in the AD, it didn't resolv the issue. Even though smb.conf dictates that the user have to a member of a group with that name. Using getent group, we can see the group. Does Samba hold on to the SID of the group somehow?
Is there a way to get those lost groups in AD;)
Regards,
Praveen Ghimire

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
