This is a very serious bug. I tested with couple computers to which only addition after standard installation was NIS and NFS and the error is always there. Local users can login to gdm3 session but NIS users cannot and the error is always the same. If this is a single issue I could live with it replacing gdm3 with lightdm but I am sure this will create other problems and I also found that the NIS users cannot open teamviewer session.
