  21 * @brief        Pull a dcerpc_auth structure, taking account of any auth
  22 *               padding in the blob. For request/response packets we pass
  23 *               the whole data blob, so auth_data_only must be set to false
  24 *               as the blob contains data+pad+auth and no just pad+auth.
  25 *
  26 * @param pkt            - The ncacn_packet strcuture
  27 * @param mem_ctx        - The mem_ctx used to allocate dcerpc_auth elements
  28 * @param pkt_trailer    - The packet trailer data, usually the trailing
  29 *                         auth_info blob, but in the request/response case
  30 *                         this is the stub_and_verifier blob.
  31 * @param auth           - A preallocated dcerpc_auth *empty* structure
  32 * @param auth_length    - The length of the auth trail, sum of auth header
  33 *                         lenght and pkt->auth_length
  34 * @param auth_data_only - Whether the pkt_trailer includes only the auth_blob
  35 *                         (+ padding) or also other data.
  36 *
  37 * @return               - A NTSTATUS error code.
