Domain join failed

UCS - Univention Corporate Server
#1

Hello
I tried to join an Ubuntu 16.04 to UCS domain. After installing the Univention Domain Join app I have the message “The domain join failed”

This is the log file

Solved
For Ubuntu 16.04…
Edited file /run/resolvconf/interface/NetworkManager and updated like so :

#nameserver 127.0.0.1
nameserver ucs_ip like 192.168.x.x

Edited file /run/resolvconf/interface/enp3so.inet [could be other .inet file depending of your interface] and updated like so :

nameserver ucs_ip  --> added this line
nameserver 8.8.8.8
nameserver 8.8.4.4

Edited /run/resolvonf/resolv.conf and updated like so :

nameserver ucs_ip --> added this line
nameserver 8.8.8.8
nameserver 8.8.4.4
search ucs_domain your_isp

Where ucs_domain could be : my_ucs.intranet
Where your_isp could be voo.be (I am living in Belgium)

Then restarted the networking service: sudo /etc/init.d/networking restart
Then launched “Univention domain join” and give root pwd then filled in the ip address of the ucs and Administrator pwd.
Join was successful
