Samba runs on Unix and groups cannot own files on Unix, so Domain Admins is mapped as ID_TYPE_BOTH in idmap.ldb on the DC, this makes Domain Admins a group and a user. If you give Domain Admins a gidNumber attribute, it becomes just a group and cannot own files.

Now I am confused. Reading "Adding a share" on domain member here:

https://wiki.samba.org/index.php/Setting_up_a_Share_Using_Windows_ACLs#Adding_a_Share

If with idmap-ad I do not set gidNumber to Domain Admins I will not be able to chown to that group?

Is it better to create other administrative group for managing file permissions?
