Description Nico Stöckigt

Created attachment 8413 [details]
/var/log/syslog

I configured a 'DHCP Dynamic DNS' policy for the main DHCP Service as follows by only giving a 'DDNS Domainname'. This results in a broken DHCP configuration and also a not working DHCP. Restarting the DHCP daemon will fail.
 [see attachment for relevant syslog]

Deleting the entire entry seems not to be sufficient: 
 # udm policies/dhcp_dnsupdate remove --dn "cn=DNS-Suffix,cn=dnsupdate,cn=dhcp,cn=policies,dc=nvsx,dc=local" --recursive --remove_referring

But I found out, that restarting the DHCP daemon twice might fix the problem.

You MUST quote the domain name, see Bug #16798 comment 1.

And before you ask: With "dhcp statements" and "dhcp options" (Bug #32557) you can break DHCPd even more - don't use it if you don't understand the implications.
