Recently I’ve been playing around with Open Enterprise Server again and I found this old article I wrote about integrating eDirectory with wireless auth.

The goal of this article is to allow you to have your wireless access protected by WPA and have users authenticate to eDirectory for access to the wireless network.
WPA (http://en.wikipedia.org/wiki/Wi-Fi_Protected_Access) is a wireless authentication standard used for controlling access to wireless networks. WPA can operate in a pre-shared key mode(router and client both know a secret password), or authentication can take place with a RADIUS server.
