obviously is to make steamdid to player be passed thru valve not the game server, that's the only one reliable way
status cmd->ask valve server-> get response from valve server without touching gameserver anyhow
LOL. So the client authenticates itself to Valve, then it's able to connect to your server, then you can't use the authentication information on your server. Great!
The point here is the information at server-side. There's no way to avoid that.
