Hi Rowland, thanks for your answer.

I don't think so because in "/etc/ini.d" both scripts (samba4 and 
samba-ad-dc) exist and are different. The difference is "samba4" does 
the check of server role and start corresponding daemons in each case 
(samba if it is a DC, or smbd-nmbd-winbind if it is a member) and the 
original samba member service daemons are masked as
well.

They are. All of them are running as expected.

We chose "linux schools distro" only for samba. We chose it because it
has the latest distribution.

Is there another better distro with latest samba for ubuntu 22.04?

Hang on, if I remember correctly, doesn't Linux schools (was karoshi)
have separate packages for a DC and the clients ? If this is the case,
what is such a script doing on on a DC?
Having said that, how a distro starts Samba has nothing to do with
Samba, so I suggest you ask Linux schools.

Well, at least everything is working, even if each DC is using a
different script.

Not sure why you are wedded to Ubuntu 22.04, but that is your choice.
However, while not a distro, the Debian Samba maintainer provides
up to date Samba packages for Ubuntu, see here:
