I have a UCS PDC and BDC on the same subnet.
I an separate subnet I have a UCS slave server. I had to install it on the same subnet first and move it afterwards. Otherwise I could not get the domain join work during installation. After the move I could login to the UCS Web Console. Fine.
Now I wanted to provide a file share from that UCS slave and therefor installed
univention-samba4 from the command-line. But the join scripts could not execute. They failed because the nameserver does not resolve the hostname of my master. So I added a second nameserver that does.
# ucr set nameserver2=my-master.local.domain
Still not working. Only if I switch nameserver1 and nameserver2 values in UCR it can resolve.
Is that a bug? Or did I do something wrong?
