As far as I'm aware RDP is a fully encrypted channel, so any failed
login messages are sent by the server to the client over that encrypted
channel. In other words, it's just like SSH
ie snort can't read it.
The only way I can think of to detect RDP failed logins is to monitor
the eventlogs of Windows servers for failed login events :-(
