I have installed PowerBroker aka Likewise-open on my Ubuntu 14.04 desktop. I successfully added the desktop to the domain but I am unable to login as a domain user at login screen. I found some answers on other posts saying to edit the 'lightdm' file but 14.04 has no such file.

Any help would be appreciated.

To actually perform a GUI Logon on Ubuntu 14.04 with an Active Directory User edit 50-ubuntu.conf file located in /usr/share/lightdm/lightdm.conf.d/ path and add the following lines then reboot to apply changes.


  • I think you forgot to include the "following lines" to be added to the file :)

make sure you are connected to the domain.

use kerberos, apt-get install krb5-user, it will ask you to enter your domain during config.

Afterwards, you run kinit and check that you are actually connected to the domain.
