[Samba] samba-ad-dc.service: Got notification message from PID 27448, but reception only permitted for main PID 27410

[L.P.H. van Belle]

Already on it.

Quick (and dirty) fix is : 

sed -i 's/Type=notify/Type=Fork/g' /usr/lib/systemd/system/samba-ad-dc.service 
systemctl daemon-reload
systemctl restart samba-ad-dc


A "better" override fix.. I personaly use this, i try to "not" touch the original supplied files.

systemctl edit samba-ad-dc.service
[Unit]
# Start bind9 always before samba-ad-dc starts (in case of bind9_dlz)
After=network.target network-online.target bind9.service

[Service]
# Temp fix ad-dc : reception only permitted for main PID
Type=Fork


Save
systemctl daemon-reload
systemctl restart samba-ad-dc

New versions soon.

Louis
