Click on the Update button.
After finishing your configuration, you should log off the Zabbix web interface.
Try to access the Zabbix server URL and verify if the Apache web server will request you to authenticate yourself.

In order to authenticate an account using Radius, the User account MUST EXIST in the Radius USERS file and on the Zabbix Local database.
If you configure the Radius authentication, this does not mean that you don't need to create the Account locally on the Zabbix dashboard.
