That's exactly what Alan is saying:
store your passwords in the LDAP as NT-Password or LM-Password

... although in my expreiments NT-Password alone is enough, but
LM-Password alone is useless.

How can you create NT-Password? One way to do that is by hijacking the
process where user enters password as plaintext (e.g. from the
password prompt when user change their password) and use smbencrypt
(part of freeradius)

Where do you store NT-Password in LDAP? In ntPassword or
sambaNtPassword LDAP attribute (or any other attribute of your choice,
as long as you remember to update raddb/ldap.attrmap as well)

If you have NT-Password, then you don't need user's cleartext password
anymore, and you don't even need any helper tool.
