Yes, that's exactly what I've done.Ok, my group has name "IT admins",
but logic is same;)Thank you.
However I have one more problem.
If I create new group or user and give it UID/GID, this is immediately
reachable on linux server. id user, or getent group/passwd and also
wbinfo -u/-g/-i can list info about it.
But if I assign group to user (or deassign), it spends a lot of time to
reflect this change.
nsswitch.conf is set up corectly. I tried to "net cache flush", but no
luck. Tried restart winbind service and also delete winbindd_cache.tdb
and winbindd_idmap.tdb files and
restart winbind, but no luck. Still old groups. I even tried to delete
whole /var/lib/samba directory, reinstall all packages and rejoin, but
the same. User has old groups.
BUT after few hours (I didn't measured how long it took) I tried to id
user and it has (magically) right groups.
I tested it on 3 different member servers, 2 CentOS 7 with Samba 4.4.4
and SerNet Samba 4.6.7 and 1 CentOS with SerNet Samba 4.6.7.
Have you ever heard about this behavior?

that?Do I have to change idmap backend to from AD to RID?OK, my
suggestion is to create an AD group, (again this is just a suggestion,
'Unix Admins'), give this group a gidNumber and make it a member of
'Domain Admins'. Now use this new group instead of 'Domain Admins' on
