We need also to sync machines.target status. Test case: FAILED

After promote nsdc and machines.target are configured as follow:

[root@master ~]# systemctl status nsdc
● nsdc.service - NethServer Domain Controller container
   Loaded: loaded (/usr/lib/systemd/system/nsdc.service; enabled; vendor preset: disabled)
   Active: active (running) since Sat 2020-01-04 03:51:02 CET; 10h ago
     Docs: man:systemd-nspawn(1)
 Main PID: 130059 (systemd-nspawn)
   Status: "Container running."

and

[root@master ~]# systemctl status machines.target
● machines.target - Containers
   Loaded: loaded (/usr/lib/systemd/system/machines.target; enabled; vendor preset: enabled)
   Active: active since Sat 2020-01-04 02:10:17 CET; 12h ago
     Docs: man:systemd.special(7)

Jan 04 02:10:17 slave.domain.local systemd[1]: Reached target Containers.

Both services are enabled and after reboot DC can join properly. File server and samba login are working fine.
TEST CASE: OK
