Seven Free or Low-Cost RADIUS Servers for Your Enterprise Network

If you're a network administrator at any large, security-conscious organization, you've got identity management implemented for your wired endpoints. What if you want to extend this beyond your wired infrastructure, to your wireless clients? That's where a Remote Authentication Dial-In User Service (RADIUS) server comes in: Your wireless access points will act as RADIUS clients, giving your users access to your network with their existing identities. If you haven't implemented RADIUS yet, here's how it works: Wireless devices connect to a wireless access point using a RADIUS client. The RADIUS client requests a set of credentials from the user. When the user types in the username and password, the RADIUS client passes the credentials to the RADIUS server The RADIUS server will apply network policies and pass the credentials to the identity management server, e.g.Active Directory Domain Services. The identity management server passes back the authorization to the RADIUS server. The RADIUS server confirms network connection with the client. The RADIUS client connects the mobile device's wireless adapter to the network.
