Hi all, We have a PDC with Samba 3.0.22-13.16 with an LDAP server working fine with no problem. We also have a BDC on a remote office and some workstation just cannot log into the domain. The only solution is to delete machine from domain, reboot, and join the domain again. We have a message into samba log : _net_auth2: creds_server_check failed. Rejecting auth request from client. Has anyone ever experienced it ? Think this could become from the password server or ldap backend but not sure. Here my smb.conf Thanks for your answers -------------- next part -------------- # Global parameters [global] admin users = root netbios name = stpc07 interfaces = eth2 workgroup = DOMAIN server string = Serveur PDC Chomarat GNU/Linux ldap passwd sync = Yes passdb backend = ldapsam:ldap://127.0.0.1 ldap admin dn = cn=admin,dc=chomarat,dc=lan ldap suffix = dc=chomarat,dc=lan ldap group suffix = ou=Groups ldap user suffix = ou=Users ldap machine suffix = ou=Machines ldap delete dn = Yes wins support = Yes name resolve order = lmhosts host wins bcast time server = Yes add user script = /usr/sbin/useradd -s /bin/false -M %u add group script = /usr/sbin/groupadd '%g' add user to group script = /usr/sbin/usermod -G `/usr/bin/id -G '%U' | /bin/sed 's/ /,/g'`,'%g' '%U' add machine script = /usr/sbin/useradd -s /bin/false -M %u logon script = %U.bat logon path domain logons = Yes os level = 340000 lm announce = Yes preferred master = Yes domain master = Yes local master = Yes dns proxy = No security=user ldap ssl = no panic action = "/usr/share/samba/panic-action" create mask = 0777 directory mask = 0777 log level = 1 nt acl support = Yes guest ok = no #Repertoires [netlogon] comment = Fichiers Scripts de Login path = /home/netlogon browseable = no read only = Yes write list = erival, Administrateur [log] comment = Repertoire de log path = /home/log browseable = no read only = No guest ok = yes -------------- next part -------------- [global] # Nom du domaine workgroup = DOMAIN netbios name = Sctc01 server string = Serveur Samba Tunisie nt acl support = Yes security = user domain master = no domain logons = yes idmap uid = 10000-20000 idmap gid = 10000-20000 winbind separator = / logon path logon home logon script = %U.bat password server = 10.1.0.41 passdb backend=ldapsam:"ldap://10.1.0.41 ldap://10.6.0.41" ldap admin dn = cn=admin,dc=chomarat,dc=lan ldap suffix = dc=chomarat,dc=lan ldap group suffix = ou=Groups ldap user suffix = ou=Users ldap machine suffix = ou=Machines create mask = 0777 directory mask = 0777 wins server = 10.1.0.41 load printers = yes printing = cups [netlogon] comment = Fichiers Scripts de Login path = /home/netlogon browseable = no read only = Yes write list = erival, frjaune, Administrateur
