This is just a bit non-stright (there's a bug report asking to
automate this in terms of menu-point-n-click).

The thing is that samba comes with 2 conflicting services:
regular file server (smbd/nmbd) and ad-dc (samba-ad-dc).
When you install the package fresh, samba-ad-dc service is
masked because you need to configure it first.

Stop smbd & nmbd & winbind.  Mask them:
   systemctl mask nmbd smbd winbind.

Yes, stop and mask them, - you don't need them.

Check that you have samba-dsdb-modules and samba-vfs-modules
installed too, just in case, and libnss-winbind.

Join the domain with samba-tool (*removing* /etc/samba/smb.conf, -
yes, samba-tool will create it).

Review the configuration, maybe adding something.

Unmask samba-ad-dc and start it.

All these services comes in a single package. I don't quite
like it, but this is what we have, and it's difficult to do
something with that now.

I mean, it'd be more productive to have, say, samba-fileserver
package and samba-ad-dc package, with semi-automatic setup and
service enablement/disablement for the given services - by
splitting them now I'll break systems on upgrades.

BTW, it's interesting how other do set up samba ad-dc on
debian and debian-like systems.
