[Samba] Samba 4.7.4 + bind9 DLZ /backend/ dropping delegated domain

Tue Jan 30 10:18:24 UTC 2018

Hai, 

Check the content of : 
/etc/logrotate.d/named 

If you see
postrotate
   /etc/init.d/smbd reload > /dev/null
endscript

Change that to 
postrotate
  if [ -d /run/systemd/system ]; then; systemctl -q is-active named && systemctl reload named; else; /etc/init.d/named reload ; fi'; 
endscript

Its something like that, so who pointing.. That does not matter, because this is OS related. 
Lots or scripts use /etc/init.d or service .....  
These need to be changed to systemd, if your using systemd, and i guess you do. 

Now, monitor your logs and observice which script is wrongly reloading. 
And report a bug to the packagers. 

And my samba 4.7.4 on debian has this in logrotate.d

/var/log/samba/log.smbd {
        weekly
        missingok
        rotate 7
        postrotate
                [ ! -x /usr/bin/smbcontrol ] || /usr/bin/smbcontrol smbd reload-                                                                                                                               config
        endscript
        compress
        delaycompress
        notifempty
}

/var/log/samba/log.nmbd {
        weekly
        missingok
        rotate 7
        postrotate
                [ ! -x /usr/bin/smbcontrol ] || /usr/bin/smbcontrol nmbd reload-                                                                                                                               config
        endscript
        compress
        delaycompress
        notifempty
}

/var/log/samba/log.samba {
        weekly
        missingok
        rotate 7
        postrotate
                if [ -d /run/systemd/system ] && command systemctl >/dev/null 2>                                                                                                                               &1 && systemctl is-active --quiet samba-ad-dc; then
                        systemctl kill --kill-who all --signal=SIGHUP samba-ad-d                                                                                                                               c
                elif [ -f /var/run/samba/samba.pid ]; then
                        # This only sends to main pid, See #803924
                        kill -HUP `cat /var/run/samba/samba.pid`
                fi
        endscript
        compress
        delaycompress
        notifempty
}
