Hey Mike,I think, you misunderstood the problem (I didn't communicate it clearly enough). The problem is not resolving ldap(.intern) on TJENER or clients. Thats working.
--- locadm@tjener:~$ ping ldap.intern PING tjener.intern (10.0.2.2) 56(84) bytes of data. 64 bytes from tjener.intern (10.0.2.2): icmp_seq=1 ttl=64 time=0.056 ms --- --- locadm@tjener:~$ ping ldap PING tjener.intern (10.0.2.2) 56(84) bytes of data. 64 bytes from tjener.intern (10.0.2.2): icmp_seq=1 ttl=64 time=0.089 ms ---isc-dhcp-server does not resolve 'ldap' (anymore?), therefore the 'Could not get Tjener LDAP object' error message.
I also couldn't find an extra search domain option. So maybe this is an upstream bug?
And the easiest fix would be using 'localhost' (like the dhcpd examples are suggesting) or 'ldap.intern' for ldap-server.

And if not, we need to find out why it is not there:``` nameserver 127.0.0.1 search intern ``` Please revisit and find the deeper solution to this problem. Thanks! Mike
