Comment 17 for bug 944041

This seems to have solved my problems:
https://help.ubuntu.com/community/LDAPClientAuthentication

I am using Ubuntu Precise (12.04) and I can successfully authenticate using ldap accounts.
Previously after login in, the computer would just hand and show the lightdm/kdm background.

I tested it to work with kdm and lightdm. I first did the lightdm config mentioned here and then
went on to the instructions.

 I just seem to have a shutdown issue now. Users can't shutdown the computer after login.
