yes I know. if the users are ignored, they can not login. in my
case, all users can login, so I didn't notice the difference. until I
found "getent passwd" and "id xxxx" are not working.
with "unix_primary_group =no", all users need to have a valid primary
group id. but maybe now there are new method to setup primary group id
I don't know. in old days we need to use windows ADUC or ldbmodify to
set up primary group id. or as you said, let "domain users" has an
rfc2037 gid. they are working fine until recent 4.6/4.7
