Since windows by default only sends encrypted password hashes across the
net, it will be impossible to check passwords on the server side. The ldap
only stores lanman and nt hashes, except your users change their passwords
from a *nix shell.

You will have to employ poledit to generate a useful ntconfig.pol which has
to be present in the netlogon share of your DC. There are some basic
password checks you can configure there, but they take place at the local
Ldap can, however, enforce password changes due to the timestamps it stores
for password hash changes.
