Ok, I just opened a bug over there. But in the meantime found out that:

Systemctl status samba.service 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.

Any hints from anybody?
Thank you

It sounds like Samba starts before the network is up.

Can you have a look at the *.service file in /usr/lib/systemd/system/
that starts Samba? Does the file contain an "After=" line that tells
the
service to start after the network? If not, copy the *.service file to
/etc/systemd/system/ and add the entry, similar to:

Here is the file
cat /usr/lib/systemd/system/samba.service 
[Unit]
Description=Samba AD Daemon
After=syslog.target network.target

[Service]
Environment=KRB5CCNAME=FILE:/run/samba/krb5cc_samba
Type=notify
NotifyAccess=all
PIDFile=/run/samba.pid
LimitNOFILE=16384
EnvironmentFile=-/etc/sysconfig/samba
ExecStart=/usr/sbin/samba $SAMBAOPTIONS
ExecReload=/usr/bin/kill -HUP $MAINPID

[Install]
WantedBy=multi-user.target


The original problem aside, I do not understand the line:
Environment=KRB5CCNAME=FILE:/run/samba/krb5cc_samba

the file /run/samba/krb5cc_samba does not exist while samba is running

But perhaps it is irrelevant?

Thnak you for comments
