And the ddns update from my server1 is without any denied messages (server1 has the static IP 192.168.178.130). My client1 windows7 brings first the denied message with a static ip and then it's doing the updates. And at this point i thougt you said my configs are ok, or the best i can get with static IPs :-)

It seems that my client is doing the ddns updates instead the script in the dhcp-config. :-) But i don't know why. I think the exit 256 message is the problem. My dhcpd-user has rw rights on the sh-script and recursive on /etc/dhcp and now the sh-script is under /usr/local/sbin as rowland said.

Your confused, I think just about everybody is confused here ;-)

And yes, you can only use one, either get sssd to update the forward and 
reverse zones OR use the setup I use. You cannot use both.
