Hello,

I have been unsuccessfully been trying to add Zentyal 4.2.2 to my existing test domain.

At the moment i am stuck at resolving the Domain controller FQDN. /var/log/zentyal/zentyal.log throws these errors:
Code: [Select]
INFO> Provision.pm:810 EBox::Samba::Provision::checkAddress - Resolving silver.mydomain.local to an IP address

Problem is that is does resolve, in the web UI and using dig.
Code: [Select]
dc-admin@zentyal:/var/log/zentyal$ dig silver.mydomain.local @192.168.178.5

; <<>> DiG 9.9.5-3+zentyal-Ubuntu <<>> silver.mydomain.local @192.168.178.5

How can I fix an error that doesn't seem to exist?

Located the problem. My DC DNS apparently took too long to reply at 7msec, Zentyal provisioning times out after 5 msec.

I changed the following lines around row 839, from 5 to 50.
Code: [Select]
       $resolver->tcp_timeout(50);
        $resolver->udp_timeout(50);

Subsequently, I also had to follow the nsupdate fix in https://forum.zentyal.org/index.php/topic,23895.15.html by removing -l. Now I have a joined domain.
