No, there will be a default policy in place.

If you'd try a recent samba release for one of the SUSE products, the user
attemptimg to change a password would get delivered with the same amount
of information (explaining why the password change has failed) as you
would get on Windows XP.

Look for the 3.0.22 or 3.0.23pre1 download links on:

No, as Windows workstations change a user password using MSRPC protocolls
as well.
