[abelahcene <abdelkader.belahcene@iap.dz>]

Hi,
I want to log from light client (diskless terminals),
on one machine , simple PC the connexion is Ok, I received the gdm login,
on
another machine server , the connexion is possible from a PC but not 
from light client, it just blinking.
May be a gdm problem, version 2.16, gnome-core 2.14;
thanks a lot
