For today’s tutorial, I am going to show you how to install and test a Windows 2008 RADIUS server. It is pretty simple and quick.
First of all, RADIUS (Remote Authentication Dial-In User Service) is a networking protocol that supports centralized AAA (Authentication, Authorization and Accounting) management. It utilizes a central database to authenticate remote users. Watch the video below to get more information on how RADIUS works.
So, what will I be doing with this RADIUS server? I have created a RADIUS server to have user authentication on the Ubiquiti Unifi AP. The primary goal of this project is to have all of the official devices (laptops, servers, etc) to be connected to one SSID while the personal mobile devices be connected to another, which will be outside of the office’s local network. Users will connect to the WIFI on their official laptops and will have to authenticate themselves before being connected to the Internet. This is where RADIUS will come to play. When the user enters their username and password, Ubiquiti will send the credentials to the RADIUS server and the server will then check for authentication.
Okay, so this tutorial will be slightly different. Instead of giving you step by step instructions, I will post a YouTube video instead. I find that watching videos and following them are a lot more helpful than reading step by step tutorials. Note that there are three major steps to this tutorial – enabling the service on the Windows Server, configuring the RADIUS service (clients and policies), and testing the RADIUS login.
To test the RADIUS login, I used NTRadPing, which is a free software from Mastersoft-Group. It will allow you to test whether or not the RADIUS server that you have configured is connected. You can download the software here.
