How do I unbind a local user from an Open Directory user?

Question

I have a couple MacBook Pros running Leopard that successfully bound a local account to a corresponding Open Directory account using Directory Utility.
I had to re-install Leopard Server (using Standard configuration) and re-create Open Directory accounts. Now these laptops are unable to bind to the new Open Directory accounts. They receive an error that the Open Directory user ID and password provided is incorrect. In addition the local user can no longer reset or change their password. I'm thinking this is because their local accounts are still bound to the old Open Directory accounts that no longer exist. Is there are way to unbind a local account in Leopard that has been bound to an Open Directory account via the Directory Utility.

Answer 1

What account are you using to bind the machine? When binding you must authenticate using the OD admin login which is usually setup as diradmin or as the current client you are logged into the machine with, but this client needs to exist on the OD server.
