I am preparing to migrate a samba 3.0.x PDC and will be using ldap passdb. I want to set up LDAP right away but let the current PDC continue servicing the domain until I am ready to make the final switch which may take a few weeks since I am not under undue pressure to switch them over. The current PDC is simply smbpasswd passdb. I can set up the LDAP and migrate the users & workstation accounts but I am reasonably certain that the workstation accounts passwords will change during the time period so I am wondering if there is something simple that I can do to prevent the workstations from changing their passwords in the interim.
