Tried to Join a Domain as Secondary but I Was Not Able

[fabio_dalfonso]

Hi,
I am trying zentyal before going on the final setup, but I was not able to join the server to a windows 2012 R2 PDC, as secondary.

I am now getting now that samba is not running, with an error of untrusted domain, and anyway, after the attemp to join, I tried to use manage under users and got, " you have to enable the module, to proceed" but the module IS checked.

What am I missing?

Thanks in Advance
Fabio
