Hi
Yes, thanks for the translation. That's it. What we don't understand is
what the OP is trying to update as he doesn't have any clients that need
updating. Maybe he has dhcp on the DC too and will update in situ? But
wait, this originated as a sssd ddns update problem. Anyway, it's far
too hot over here for surmising. Everyone else has gone to the bar:(
Cheers,
Steve
