By default Samba 4 uses its own built in LDAP server and the OpenLDAP
backend is currently not working properly.
I have managed to migrate users from an Apple Open Directory server
(which is based on MIT Kerberos and OpenLDAP) to Samba 4, but I was
only using Open Directory for authentication of one service. No
machines joined to OD or anything like that.
All I needed to do was dump the kerberos database, import it to
Heimdal, dump it from Heimdal again and then use the password hashes
from the Heimdal dump to create the necessary unicodePwd attributes in
Samba's directory. After that I used ldapsearch to get hold of the
groups each user was a member of and then used ldbmodify (or perhaps
ldapmodify. I can't remember now) to migrate them to Samba.
I've never used Samba 3 as a PDC, so I'm not sure what the LDAP schema
looks like and how it differs from what Samba 4 uses, but as long as
the password hashes are in a compatible format, I imagine it's just a
matter of slapcat or ldapsearch, munging the results and then
ldbmodify to add the users to Samba 4.
I don't know of an existing script to do this.
