Migrating from Apple OpenDirectory?

[Michael Wood]

Hi

We have an Apple Open Directory server that we'd like to migrate to
Samba 4 (for authentication.  No file/print.)  OpenDirectory is based
on OpenLDAP, but the passwords are not stored in the LDAP directory,
as far as I understand it.

Is there any way to migrate the accounts to Samba without having to
reset all the passwords?

I see some mention in the Open Directory Admin document of running
Open Directory as an NT-style PDC or BDC, so is it possible to turn it
into a PDC and then migrate from that to Samba 4?

Thanks.
