[Samba] password capture / synchronisation

[Simon Oliver]

On the Windows PDC I can use a filter DLL to capture password and sync them
to the LDAP server.

I want to replace my current Windows NT4 domain controller with a samba
based PDC utilizing LDAP.

How can I capture samba password changes so that I can update the LDAP
passwords.  And similarly, how can I capture LDAP password changes to update
samba passwords?

Thanks
