I am trying to setup windows server for FAST encrypted channel support to
test OTP pre authentication in kerberos.

I have already tested on linux machine by deploying KDC using krb5-1.12.1
source code, freeradius server and using keytab of service principal to
receive armor ccache to be used to establish FAST encrypted channel between
client and KDC.

I have setup windows server 2012 for kerberos, and added support for "KDC
support for claims, compound authentication and Kerberos armoring" policy
on it. I can receive TGT for service principal. But, when I execute the
command "kinit -T <armor-cache> <principal>", KDC does not reply with any
padata and no FAST encrypted channel is established (observed through
wireshark log and Kerberos library logs).

Is it possible to establish a FAST encrypted channel between linux client
and Windows AD? Have I missed any setting?
