SAP SNC-RFC with Kerberos?

[Barbat, Calin]

Hello to everyone,
has somebody succeeded in securing RFC connections between two SAP R/3 instances by using MIT Kerberos? I'd be interested in how it's done.

My KDC is a Win2K3 AD and the two application servers to be connected are running on Solaris respectively Linux.

BTW: Do I need proxyable or forwardable tickets in order to do this?
Can kinit put two different credentials in the same cache?

Best regards,

Calin Barbat.
