GetMSCacheTicketFromCacheInfo() uses the tktinfo->TicketFlags as the
value to assign to TicketRequest->TicketFlags.  This field is blindly
inserted into the kdc-options[0] field of the TGS_REQ.  If there are
bits such as TRANSIT_POLICY_CHECKED in the TicketFlags, this will result
in an unknown TGS_OPTION being processed by the KDC.
