Before we can proceed any further, we need to reset the users in Atavism and allow the web server to control our users logins. In order to do that, follow through this process. We have to do this so that the Atavism players have the same ID as the web server users. If you do not do this, you will not see players, the players will line up to the wrong users, the player may end up with other users characters and you may edit the wrong player in the system.
Once you have cleared your users, restart your game server. Once the game server comes online you will be able to authenticate with your website users logins into the game server. You do not need to change anything in the client.
