Tutorial: Adjusting Authentication and Database Connection Settings⁠

• An installed Access Server.

• Console access and the ability to get root access.

1. Connect to the console and get root privileges.

2. Increase the maximum number of database connections with this command:

   sacli --key "mysql.max_overflow" --value "25" configput
   systemctl restart openvpnas

   • This command sets the QueuePool size to 25. Adjust the number as needed. The default is 10.

   • Ensure to restart the service to apply this change.

1. Increase the number of authentication threads with this command:

   sacli --key "auth.module.max_parallel" --value "25" configput
   sacli start

   • This command sets the number of parallel authentication threads to 25. Adjust the number as needed. The default is 8.

   • Restart the server to apply the changes.

By following these steps, you can effectively manage and optimize the performance of your Access Server under high-load scenarios or with slower authentication systems.
