[Samba/AD] Authentification refusée

Bonjour,

je dispose d'un serveur Samba en RHEL 4.6. C'est un serveur qui doit être accessible à un groupe de mon domaine Active Directory. Cela fonctionne pour les 2 personnes de l'AD qui avaient testé la connexion et dont leur user avait été directement intégré dans la conf Samba. On a remplacé ces 2 users par un groupe de l'AD dont ils font aussi partie. Pour eux, il n' y a pas de souci, ça fonctionne encore. En revanche, pour les autres du groupe, impossible de se connecter. Depuis mon poste XP, j'ai l'invite login/password mais elle continue de se réafficher sans message d'erreur. J'ai donc suivi tutorial pour tenter de refaire entièrement et correctement la config. Il m'a fait progresser énormément puisqu'auparavant la commande wbinfo ne remontait rien. Aujourd'hui, je vois bien tous les groupes et users de l'AD depuis mon serveur Samba. En revanche, je n'arrive toujours pas à m'authentifier, j'ai toujours le même symptôme.

Je me tourne vers vous pour me venir en aide, car là je suis à cours d'idée surtout que Kerberos n'est pas trop ma tasse de thé.

Merci d'avance.

Edit : Je viens de voir que mon fichier nsswitch.conf n'était pas correct. Je viens de modifier :

Citation:

passwd: files
shadow: files
group: files

par

passwd: compat winbind
shadow: compat
group: compat winbind

Edit 2 : J'ai redémarré le bouzin et toujours pas mieux, je me dirige maintenant vers le répertoire /etc/pam.d, je pense qu'il me manque des choses au particulier du côté du fichier samba qui ne contient "que" ça :

Citation:

auth required /lib/security/pam_stack.so service=system-auth
account required /lib/security/pam_stack.so service=system-auth

Edit 3 : J'ai le message suivant dans mes logs :

Citation:

Username XXXXINTRA\LOGIN is invalid on this system

Si je comprends bien, cela veut dire que Redhat ne trouve pas de compte correspondant dans /etc/passwd (ce qui est normal) ou que Redhat ne lui crée pas automatiquement de compte avec un uid/gid assocé. J'ai pourtant les lignes suivantes dans mon ficheir smb.conf :

Citation:

idmap uid = 100000-200000
idmap gid = 100000-200000

J'ai créé un user (adduser) avec mon login. Je me suis connecté sans problème au répertoire partagé. Je l'ai supprimé, j'ai de nouveau le problème. Il y a donc bien un problème de mappage au niveau des mes utilisateurs de l'AD. Cependant, je ne comprends pas ce qui pourrait bloquer ce mappage.

Mon fichier smb.conf (il y a plusieurs paramètres que je ne maitrise pas) :

Citation:

[global]
workgroup = XXXXXXINTRA
realm = XXXXXX.INTRA
server string = serveur %h (Samba %v, Ubuntu)
security = ADS
password server = xxxxxxxxxx-dc-01.xxxxxxxx.intra xxxxxxxxx-dc-02.xxxxxxxxx.intra
passdb backend = tdbsam
log file = /var/log/samba/%m.log
max log size = 50
preferred master = No
local master = No
domain master = No

idmap uid = 10000-20000
idmap gid = 10000-20000

winbind separator = /
winbind cache time = 10
winbind enum users = Yes
winbind enum groups = Yes
winbind use default domain = Yes
cups options = raw

read only = No

[printers]

[xxxxxxxxxxxxx]

[xxxxxxxxxxxx]
path = /xxxxxxxxxxxxxxxxxxxx
valid users = @XXXXXXXXXXXXINTRA\GG_xxxxxxxxxxxxxx
force group = tomcat6
read only = No
create mask = 0660
hide files = /lost+found/
browseable = No

Edit 4 : Je viens de modifier le paramètre security. Je suis passé de la valeur ads à domain. Les commandes getent fonctionnent maintenant. Je vois que seulement 6 utilisateurs peuvent potentiellement utiliser Samba mais je ne comprends pas pourquoi ce n'est pas l'ensemble (je ne parle pas pour le moment d'accès aux répertoires partagés, je parle juste des utilisateurs qui sont mappés par winbind).

Edit 5 : la machine commence à avoir raison de moi et ça ne me plait pas. J'ai repassé la variable security à la valeur ads, autrement j'avais une erreur dans le join. Le fait d'avoir modifié mon nsswitch.conf m'a permis de faire fonctionner les commandes getent. Cependant, j'ai toujours un gros souci. En effet, les commandes wbinfo -u et -g me retournent 6080 et 1965 enregistrements. Quand j'effectue les commandes getent passwd et getent group, je n'ai que 45 et (dont 6 du domaine) et 402 enregistrements. Je n'arrive pas à expliquer cette différence.

Edit 6 : Ce matin, ça fonctionne pour 3 des 4 valid users présents dans le smb.conf (nous avons mis de côté le groupe GG_XXXXX). Je suis le 4ème :-)). Quand je tente de me connecter voici les logs (level 3) :

J'ai donc en particulier l'erreur suivante :

Le log m'indique donc que mon samba ne peut pas m'autoriser (NLEXXXXXX) à me connecter car il ne me connait pas. Est-ce Winbind qui ne fait pas correctement son boulot en ne m'attribuant pas d'uid/gid sur le serveur Samba ? Dans ce cas, pourquoi le ferait-il pour certains utilisateurs et pas pour d'autres ?

Merci.

Edit 7 : J'ai réussi à corriger le point indiqué en Edit 5. Je n'avais pas supprimé tous les fichiers de cache d'où mon erreur. Liste des fichiers :
