Called after a client's auth ID has been validated. The state of a client's authorization as an admin is not guaranteed here. Use OnClientPostAdminCheck() if you need a client's admin status. There may be a delay in receiving this callback if the Steam netowrk is experience downtime or other issues. This is called by bots, but the ID will be "BOT".
