Cross realm between AD and MIT

[Wilper, Ross A]

One thing that you did not make clear is if you defined the MIT kerberos realm in the registry of the Windows 7 machine.
(ksetup /AddKDC <realm> <kdc> or just go to HKLM\System\CurrentControlSet\LSA\Kerberos\Domains and make a key named the same as the realm and add a REG_MULTI_SZ value "KdcNames")

I can't open a session with user1 (MIT principal).
