Title:
  cannot start X session with NIS account

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  When login with a NIS account, X does not start, or more precisely it
  starts and exits immediately.

  Only errors in logs is:
   (EE) systemd-logind: failed to get session: PID 4335 does not belong to any known session

  X11/gdm login works fine with local accounts.

  SSH/terminal console login with NIS accounts works fine.

  /etc/X11/Xwrapper.config:
    allowed_users=anybody

  I've seen several reports of such problems under other versions (eg
  19.10), but no working solutions was found. It seems that the problem
  is the same with lightdm.
