Our unit files don't seem to specify that we need the network to be operational.  Apparently systemd is really verbose about this, but it's an easy fix.

Systemctl status samba shows the following as well:

feddc samba[658]:   task_server_terminate: [KDC: no network interfaces configured]

It seems to correspond to samba/source4/kdc/kdc-service-mit.c

/* Load interfaces for kpasswd */
	load_interface_list(task, task->lp_ctx, &ifaces);
	if (iface_list_count(ifaces) == 0) {
		task_server_terminate(task,
				      "KDC: no network interfaces configured",
				      false);
		return;
	}


But I have no skills to fix it

I have try this patch and now, when I stop/start the server, all work fine.

I have remove my workaround and replace the original samba.service file.

Then I have try to stop and start the addc server: krb5kdc wont start with "KDC: no network interfaces configured" error like as expected.

Then I have add the "network-online.target" string to After= without add the Wants= directive.

Stop the server and start it and krb5kdc start and all work fine.

Then I have add also the Wants= directive, and the story is the same, krb5kdc start correctly.

I thing the first modify (network-online.target) is sufficiet.

At this point I have remove Wants= directive and try to stop/start the server many time and always krb5kdc is started.

NOTE:
a) after all modify to samba.service I have run "systemctl daemon-reload",
b) only a reboot it's not sufficient to check the problem, the server must be stop and started because the server is a Kvm/Qemu virtual server and the problem occur when the host destroy and recreate the interface for the virtual server.

Many thanks Andreas, I hope this help.

Wants= is needed that systemd check that the specified service is running/enabled.

Robbie, I think you want to add the changes from comment #10 also to krb5kdc.service.
