Programatically provision users to server.

Hi everyone, I am thinking of adding a FreeRadius server to an existing infrastructure in order to provision users through an application. I am currently running a WLAN controller connecting several access points. Currently users are added manually through the WLAN controller interface. Could I add a FreeRadius server and be able to programatically add users to it? I need to be able to do this through a Ruby on Rails application. I am thinking I would have to either: 1. Use some sort of API 2. Run a script that uses a command line interface Your thoughts and suggestions on this architecture would be appreciated. Thanks Matthew.
