Elektron for Mac

From Corriente Networks:

Elektron is server software providing RADIUS/802.1X authentication services for Wi-Fi networks. Using Elektron, small businesses can enable the WPA Enterprise features of their Wi-Fi hardware, including popular equipment from makers like Linksys, D-Link, Apple, Cisco, and Netgear, enhancing both network user management and data encryption. With Elektron installed, every user attempting to log on to your Wi-Fi network will be asked to provide their own username and password before being granted access. You can use your existing server logins for your Wi-Fi network credentials (including Open Directory), or maintain a separate, Wi-Fi network-only list of logins. Elektron works with Windows XP and Mac OS X clients with no additional software necessary. There are no additional per-client licensing fees with Elektron, so as your business grows, so can your network.
