2.2.2.13.2 rpc_sec_vt_bitmask

The rpc_sec_vt_bitmask structure command is defined as follows.

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5	6	7	8	9	2 0	1	2	3	4	5	6	7	8	9	3 0	1
command																length (0x0004)
bits (0x00000001)

 typedef struct {
   USHORT command;
   USHORT length;
   ULONG bits;
 } rpc_sec_vt_bitmask;

command: Least significant bits 0 through 13 MUST be SEC_VT_COMMAND_BITMASK_1. Bits 14 and 15 are as specified in section 2.2.2.13.

Note SEC_VT_COMMAND_BITMASK_1 has a value of 0x0001.

length: MUST be 0x0004.

bits: The bits field is a bitmask. A server MUST ignore bits it does not understand. Currently, there is only one bit defined: CLIENT_SUPPORT_HEADER_SIGNING (bitmask of 0x00000001). If this bit is set, the PFC_SUPPORT_HEADER_SIGN bit, as specified in section 2.2.2.3, MUST be present in the PDU header for the bind PDU on this connection. For information on how PFC_SUPPORT_HEADER_SIGN is used, see section 3.3.1.5.2.2.<41>
