Why won't Ubuntu 14.04 Desktop join an AD domain?

Question

Active Directory

There is a freshly installed Ubuntu 14.04 Desktop, there is a 2012R2 domain network. I want to join a computer to a domain using PowerBroker Identity Services, Open Edition .
Below is the full log of what happened. I want to note that once I included a server in the domain in the same way and there were no problems at all.

Answer 1

For a while, I was on the wrong track looking for a solution, trying to figure out what was wrong with Cerberus. I manipulated the configs, but it was all to no avail, nothing helped until I compared the composition of the installed packages and the configs on the newly installed server and desktop. Everything plus/minus was identical. The last resort left is to read the documentation . Previously, I was stopped from reading the documentation by the fact that it is only for the pbis edition of the Enterprise. But then I overcame myself and discovered several interesting things.
1. Installation Guide p. 32. The content of the file /etc/nsswitch.confwas just such that potentially prevented the discovery of the .local domain (just my case). Edited and continued reading.
2.Installation Guide page 33. Contents of the /etc/resolv.conf. On the desktop, it contained 127.0.0.1 as the nameserver address. This file cannot be edited by hand, I had to look, firstly, for the cause, and secondly, for a way to fix it.
The reason was found in the NetworkManager component, which on the desktop, in fact, contains a local dns server, so from this point of view, the address 127.0.0.1 is quite correct. To return the dns server address received from dhcp, you need to:
edit /etc/NetworkManager/NetworkManager.conf:
comment out the following line:
After that, it remained to restart NetworkManager:
After restarting, the contents of the file /etc/resolv.conftook on the appropriate form, pbis was installed correctly, and after rebooting the computer joined the domain perfectly.
