Connexion via LDAP via CentOS 5 [Résolu]

[kalwin]

Bonjour à tous,

Je vous expose mon souci,

Je mets en place une authentification via openldap sur mon architecture unix (AIX) - linux (CentOS)

Le serveur ldap est une CentOS (dsl pas le choix) lol

Je configure mon serveur
ldap : slapd & ldap.conf => tout fonctionne bien
je configure mon ssh : UsePAM yes

je configure mon /etc/pam.d/system-auth :

Code :

auth        requisite     pam_succeed_if.so uid >= 500 quiet
auth        sufficient    pam_ldap.so use_first_pass
auth        required      pam_deny.so
 
account     required      pam_unix.so broken_shadow
account     sufficient    pam_localuser.so
account     sufficient    pam_succeed_if.so uid < 500 quiet
account     [default=bad success=ok user_unknown=ignore] pam_ldap.so
account     required      pam_permit.so
 
password    requisite     pam_cracklib.so retry=3
password    sufficient    pam_unix.so nullok try_first_pass use_authtok
password    sufficient    pam_ldap.so use_authtok
password    required      pam_deny.so
 
session     optional      pam_keyinit.so revoke
session     required      pam_limits.so
session     optional      pam_mkhomedir.so
session     [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid
session     required      pam_unix.so
session     optional      pam_ldap.so

je configure le /etc/nsswitch.conf :

Code :

passwd:     files ldap
shadow:     files ldap
group:      files ldap

J'ai créé un compte standard : SKN55051
je procède a la migration via les outils ldap fourni
configure le fichier qui vont bien ...

Supprime mon user SKN55051 de /etc/passwd

J'importe les ldif crées via ldapadd sans souci
mon serveur ldap est redémarré, ssh aussi ,
enfin je fais (je pense tout ce qui va bien).

Mais impossible de m'identifier via se maudit ldap :

Auriez vous une idée... ?
