Content-Type: text/plain Content-Disposition: inline Content-Transfer-Encoding: binary MIME-Version: 1.0 X-Mailer: MIME-tools 5.411 (Entity 5.404) Subject: MSLSA ccache uses ticket TicketFlags as KdcOptions in the TGS request without mapping between types X-RT-Original-Encoding: iso-8859-1 Content-Length: 335 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.
