I would suggest you stop using old outdated ways of doing things ;-)

As far as I can see 'smbldap-tools' is dead, there doesn't seem to be a
home webpage anywhere and as such it is now unmaintained. It only
needs a perl update to break it.

We now move to Windows, Microsoft seems to be trying to stop NT4-style
domains working, this may be by accident, or on purpose, but it is

Can I suggest you upgrade to a Samba AD domain, it is easier to
maintain and works with current (and past) versions of Windows.
