Hey community!
I'm relatively new Zentyal user (few months), and I love it! But I've ran into a problem I hope someone can help me with.
In my deployment I have two Zentyal servers (`zentyal-1.mydomain.com` and `zentyal-2.mydomain.com`), both running "Domain Controller and File Sharing" service. The idea is to have primary and secondary DC controller. I was using this setup successfully for a few months, meaning that I've successfully joined several Ubuntu / Windows 11 machines to it, created several users, etc.
The problem happened today when I've tried to join another Ubuntu machine, by following the same exact steps as earlier. This time I've got an error. Here's the command and the complete output (just domain name edited):

As you can see I've used the built-in Administrator account, and according to the output it's authenticated successfully. Yet I'm getting "Insufficient permissions to join the domain".
Any help will be appreciated!
Thanks!
