Some people complain that the white list stopped working, actually the White list works fine.
We only removed the auto admin without password on GUID.
The reason is that you can spoof ID's by hacking the network data, the server would accept you, and hand you Admin.
and then you can destroy a server, ban everyone and the key auth server would only catch on that your ID is invalid in 20 to 60 seconds. and you get kicked off the server. by then the damage is done.
So the white list still works, but you need to enter the password too, its basically 2 factor authentication, you need to have the correct GUID + a password.
Also in the bottom of the scripts file is the commented out lines that auto give admin to certain GUID's in the whitelist, you can uncomment that code if you don't fear the security issue.
