To refresh the question.
Setup:
Fresh Ubuntu Server Install.
Added Ubuntu Desktop.
Added Zentyal
Setup :
DHCP (working)
Shares (working on main folder - subfolders have denied access dont know why yet.)
Users (working)
VPN (working)
The problem is on Thin Client
Everything works, boots up fine.
But I dont know what the sudo password is.
I have tried all the password that I know...
Thanks
In addition, one of the attempts to get it fix, was to remove the:
ltsp-server and Zentyal-server, and then just install Zentyal-server..
Same situation..
