MIT Kerberos and 2008R2 AD

[Hubert Chomette]

Hello there,
Is there a solution for having a MIT kdc and 2008R2 AD on the same realm?
I got an existing MIT KDC Realm and try to implement a 2008R2 AD for my windows clients.
I wish to use the MIT Kdc  as the main authentification process.
Idea is to import account with cron and ldip file to the 2008R2 AD but Authentification should continue using MIT Kdc.

Is there a solution rather than cross realm trust (which suppose différent realm name)? 

Regards,
