148 * @brief Pull a dcerpc_auth structure, taking account of any auth
149 * padding in the blob. For request/response packets we pass
150 * the whole data blob, so auth_data_only must be set to false
151 * as the blob contains data+pad+auth and no just pad+auth.
153 * @param pkt - The ncacn_packet strcuture
154 * @param mem_ctx - The mem_ctx used to allocate dcerpc_auth elements
155 * @param pkt_trailer - The packet trailer data, usually the trailing
156 * auth_info blob, but in the request/response case
157 * this is the stub_and_verifier blob.
158 * @param auth - A preallocated dcerpc_auth *empty* structure
159 * @param auth_length - The length of the auth trail, sum of auth header
160 * lenght and pkt->auth_length
161 * @param auth_data_only - Whether the pkt_trailer includes only the auth_blob
162 * (+ padding) or also other data.
164 * @return - A NTSTATUS error code.
