No, it is a bug in your smb.conf, it is incorrectly set.
First, every AD domain users primary group is Domain Users, all other
groups, a user is a member of, are the users supplementary groups.
I note you are using a red-hat distro, are you also using sssd ? If so,
I suggest you stop, especially now that you are using Samba 4.10.4. Up
until Samba 4.8.0 the smbd deamon could 'talk' direct to AD, this was
stopped at 4.8.0 and now 'smbd' has to go through winbind. This all
depends on smb.conf being set up correctly.
Your 'idmap config' lines should be similar to these:
idmap config * : backend = tdb
idmap config * : range = 3000-7999
idmap config TEST : backend = rid
idmap config TEST : range = 10000-999999
That is if you use the winbind 'rid' backend. You can find more info here:
