%client.getAuthInfo

[Ragora]

%client.getAutoInfo is a pretty big facet to the operation of Tribes 2. It pretty much allows the game server to look at a client and grab their GUID, name, etc. It is script-defined in TribesNext, but if this project were to go and eventually require an account server, this will need to be implemented. By peering at what TribesNext's variant returns, its supposed to return a tab delineated list of player information:

Name, Unknown blank Entry, TribesNext sticks a 0 here, GUID

So an example would be:
MyName\t\t0\t1234567
