[Samba] BDC and password change program

[kent]

Hello,
Just wondering what I should be using for the password change program on a BDC.
Should it be:
        passwd program = /usr/bin/smbpasswd -r <PDC address> %u

I'm having a problem with passwords not staying in sync between the PDC and BDC
with pass backend ldap.

The systems are all Fedora Core 4, Samba 3.0.14a, openldap 2.2.23
