Hi all I had a fully working samba + ldap PDC. After upgrading from 3.0.7 to 3.0.9 I have lost synchronization of samba password and ldap password. Each time a Windows Client do a password change the server samba produce the error [2005/01/13 16:26:06, 2] passdb/pdb_ldap.c:ldapsam_modify_entry(1572) ldap password change requested, but LDAP server does not support it -- ignoring I have checked permissions on attribute userPassword for ldap user used by samba for ldap binding. Is's all right, (infact with 3.0.7 the entire system worked perfectly). I've already checked the ldap's log at many differents debug levels but i didn't find any trace of denying permission or similar. I would know how I can simulate the ldap password changing as is done by samba server. Please help me. my packages version samba-3.0.9 samba-client-3.0.9 openldap2-2.2.6 openldap2-client-2.2.6 my smb.conf [global] passdb backend = ldapsam:ldap://127.0.0.1/ ldap suffix = dc=mydomain,dc=com ldap machine suffix = ou=Computers ldap user suffix = ou=Users ldap group suffix = ou=Groups ldap idmap suffix = ou=Users ldap admin dn = "uid=samba,ou=LdapUsers,dc=mydomain,dc=com" ldap ssl = start tls ldap passwd sync = yes # Script front end LDAP add machine script = /usr/local/sbin/smbldap-useradd -w "%u" add group script = /usr/local/sbin/smbldap-groupadd -p "%g" delete group script = /usr/local/sbin/smbldap-groupdel "%g" add user to group script = /usr/local/sbin/smbldap-groupmod -m "%u" "%g" delete user from group script = /usr/local/sbin/smbldap-groupmod -x "%u" "%g" set primary group script = /usr/local/sbin/smbldap-usermod -g "%g" "%u" workgroup = MYDOMAIN netbios name = BUHSERVER netbios aliases = YOUARE CLEVER comment = Linux Samba PDC security = user encrypt passwords = Yes domain master = yes domain logons = yes preferred master = yes os level = 65 wins support = yes log level = 2 auth:5 max log size = 0 printing = cups printcap name = cups printcap cache time = 750 cups options = raw printer admin = @ntadmin, root, administrator map to guest = Bad User logon script = logon.bat logon path logon drive = F: logon home = \\%L\%U\.9xprofile public = no browseable = no writeable = no min password length = 8
