In NS8 you can edit include.conf:
runagent -m samba1 podman exec -ti samba-dc vi /etc/samba/include.conf
To restart the DC
runagent -m samba1 systemctl --user restart samba-dc
I didn’t test that configuration with a multiple DC AD domain. I suppose changing that setting applies to the local DC only. In other words, it does not affect the global domain policy. Let me know how it goes!
