My school runs our WiFi network on Aruba Controllers, some of the access points are Aruba-branded and is managed. Others are D-Link branded, and need configuration one by one if needed.
We run our authentication on Captive Portal now, and is now seeing quite some slow down, we have integration with Active Directory. But it's strictly just for login and password information, and our record is small, so we can migrate to another directory or database server anytime.
Our options are limited, as there are no lots of options out there as I know of.
So, here's two ways to go. One is to stick with Captive Portal and possibly start inspecting where the slow down is. Another is to migrate out database to possibly AD with Radius and use that as our Radius server for WPA2-Enterprise.
One of my concern is overall session and bandwidth, as we have a single 3600 controller, and a little about 1500 potential users (hopefully), with WPA2-Enterprise, they will be online all the time.
Which is more preferable in a educational environment?
