Cross realm kerberos using delgation

[ankur jain]

Hi,
I am trying to do kerberos authentication in a cross realm scenario as
follows:
Domain Name : filedom(windows server 2008r2) , delegateuser at filedom.com is
setup here , will be accesing the share in this domain
Domain Name: userdom(windows server 2008r2), enduser at userdom.com is setup
here
Linux box is added to filedom.

Now sitting on linux box i get the ticket for delegate user using:  kinit
-f delegateuser at filedom.com
But while getting the service ticket using kvno the it fails in one of the
steps.

Can someone guide me how would i get the service ticket in the cross realm
scenario with or without using kvno.

It would be great if get some help on this.

Regards
