/*
|
|
* XXX - MAPI is based on MS RPC, i.e. on DCE RPC.
|
|
* Unfortunately, at least as I read the DCE RPC 1.1 spec's
|
|
* description of RPC PDUs, not all PDUs necessarily have
|
|
* an interface UUID for connection-oriented RPC, and MAPI
|
|
* runs over TCP - i.e., it uses connection-oriented RPC - so if
|
|
* somebody ever does a dissector for the MAPI RPC calls,
|
|
* it's not clear how we'd arrange to call that dissector for
|
|
* MAPI calls if we haven't seen a bind operation.
|
|
*
|
|
* Currently, the DCE RPC dissector doesn't dissect enough
|
|
* to determine what service is being called, so without
|
|
* a dissector for the TCP port TCP_PORT_MAPI, MAPI traffic
|
|
* would just be identified as DCE RPC traffic, and, as per
|
|
* the above, even if the DCE RPC dissector did dissect enough
|
|
* to determine what service is being called, we might still
|
|
* need to check the port number to recognize MAPI traffic.
