try the latest samba release and search for the ldapsync.pl

the problem is that you dont have the old password from the user
(samba starts the passwd sync program only with the new password).
there are a few ways I know how you can do it:
* make a smbadm dn and give him write permissions to the password
attributes (lmpassword, ntpassword, userpassword)
* make an acl for the ip address from your samba server and give
the server write permissions>
