Sorry for the spam, just have another question here.

What is the full/correct way to add a group then? The domain-joined 
fileserver is a Unix machine (Debian 9) with Samba 4.5.16. These are the 
*idmap*-relevant parts from the smb.conf on it:

idmap config * : backend = tdb idmap config * : range = 3000-7999

idmap config DOMAIN: backend = rfc2307 idmap config DOMAIN: range = 
10000-999999999 idmap config DOMAIN: ldap_server = ad idmap config 
DOMAIN: unix_nss_info = yes

This guide in the wiki 
(https://wiki.samba.org/index.php/User_and_Group_management) doesn't say 
much more than *samba tool group add groupname*.

All the best,
