Hi, I have configured samba as PDC server with a ldap backend. Everything seem to work correctly except that I have a recurrent samba error in the log file: [2007/10/02 16:13:25, 0] auth/auth_util.c:create_builtin_users(751) create_builtin_users: Failed to create Users [2007/10/02 16:22:41, 0] auth/auth_util.c:create_builtin_users(751) create_builtin_users: Failed to create Users [2007/10/02 16:27:37, 0] auth/auth_util.c:create_builtin_users(751) create_builtin_users: Failed to create Users [2007/10/02 16:32:58, 0] auth/auth_util.c:create_builtin_users(751) create_builtin_users: Failed to create Users [2007/10/02 16:36:04, 0] auth/auth_util.c:create_builtin_users(751) create_builtin_users: Failed to create Users [2007/10/02 16:36:04, 0] auth/auth_util.c:create_builtin_users(751) create_builtin_users: Failed to create Users The samba version is 3.0.24, (on a debian etch). my smb.conf file : # Samba config file created using SWAT # from 192.168.1.8 (192.168.1.8) # Date: 2007/09/19 12:11:58 [global] workgroup = NEXVISION server string = PE2900 PDC Server passdb backend = ldapsam:ldap://127.0.0.1/ socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 load printers = No printcap name = /dev/null disable spoolss = Yes add user script = /usr/sbin/smbldap-useradd -m "%u" delete user script = /usr/sbin/smbldap-userdel "%u" add group script = /usr/sbin/smbldap-groupadd -p "%g" delete group script = /usr/sbin/smbldap-groupdel "%g" add user to group script = /usr/sbin/smbldap-groupmod -m "%u" "%g" delete user from group script = /usr/sbin/smbldap-groupmod -x "%u" "%g" set primary group script = /usr/sbin/smbldap-usermod -g "%g" "%u" add machine script = /usr/sbin/smbldap-useradd -w "%u" logon path = \\%L\profile\%U logon drive = P: logon home = \\%L\%U domain logons = Yes os level = 40 domain master = Yes dns proxy = No wins support = Yes ldap admin dn = cn=admin,dc=nexvision ldap delete dn = Yes ldap group suffix = ou=Groups ldap idmap suffix = ou=Idmap ldap machine suffix = ou=Machines ldap passwd sync = Yes ldap suffix = dc=nexvision ldap ssl = no ldap user suffix = ou=Users winbind use default domain = Yes hosts allow = 192.168.1., 127. case sensitive = No hide files = /desktop.ini/ntuser.ini/NTUSER.*/ [netlogon] path = /home/netlogon write list = Administrateur browseable = No [profile] path = /home/export/profile read only = No create mask = 0600 directory mask = 0700 profile acls = Yes browseable = No [homes] comment = Repertoire Personnel valid users = %S read only = No create mask = 0600 directory mask = 0700 browseable = No [nexvision] comment = R?pertoire Projets Groupe NexVision path = /home/nexvision read only = No create mask = 0660 directory mask = 0770 Thanks, Guillaume.
