NIS + freeze au prompt de login

Bonjour,

Je viens avec un problème un tordu, j'espère que ça va vous plaire,

Pbm:
Lorsque je démarre ma machine, elle boot assez rapidement puis commence à afficher le prompt de login et s'arrête au milieu : freeze
Je dois attendre environ 10 min pour pouvoir me loguer normalement ... sauf que des fois ça marche bien :'(

Contexte:
C'est donc une machine d'entreprise, la première sur ubuntu, d'autres commence à arriver (pour l'instant l'autre n'a pas ce pbm et le parc est homogène : Dell)

Pour se connecter on utilise une authentification via NIS (le home est en local par contre)
J'ai donc fait la modif suivante pour avoir le prompt :

#/etc/lightdm/lightdm.conf
greeter-show-manual-login=true

Je peux par contre ouvrir une console (ctrl+alt+Fx) et me loguer avec mon user via NIS sans soucis. Et j'en profite pour regarder le syslog défiler.

Investigation:

Il y a clairement un truc avec  'rtkit-daemon[1827]: Warning: PolicyKit call failed: Did not receive a reply.' et j'ai trouvé ça qui pourrait avoir un lien, mais je ne sais pas ce que je peux faire avec : http://serverfault.com/questions/147825 … -my-ubuntu
J'imagine que ça signifie que l'user distant n'aurait pas les droits pour accéder à pulseaudio.

#super syslog un peu nettoyé :
