Possible to use the OX-User-DB (ldap) for the backend of a samba PDC?

[Mausbiber]

Hi guys,
i have a question about the User-DB in OpenXchange. By default OX stores the OX-User & Login-Data in a LDAP Database right?
So, when installing samba as a PDC for the windows clients, it's possible to told samba to use a ldap-db for user authentication.
My question is now, is it possible to use the OX-User-ldap-db with samba for user authentication in a PDC?
Perhaps somebody worked on it already and can help me with ideas or something else.
Btw. sorry for my english, i'm from germany.

Thanks

Chris
