we do this, but not in this way. the best strategy that i'm currently
aware of is not to try to make w2k authenticate straight off of LDAP (we
couldn't get that to work and i'm not sure it's supposed to work) but
rather to run samba as a domain controller and have w2k authenticate off
of samba.

so it looks something like this:

--openldap configured with the samba schema somewhere on the network.

--samba 2.2 or greater running on an OS that supports nssldap and PAM:
see for lots more detail.

--w2k and xp running in mixed authentication mode

so clients attach to the domain run by samba, samba proxies the
authentication to LDAP, but is able to get the LM hash right out of ldap
so there's no problem of unencrypted passwords on the lan (we're actually
doing this with messsy magic and synchronization to /etc/samba/smbpasswd
now, because of an older version of samba that didn't support this, but
it is *much* better if you can get the LM hash straight out of LDAP).

i find samba to be the best glue to cobble together mixed windows and
linux networks and still get all of them authenticating out of LDAP.

hope that's a useful direction.
