I have a Cisco WAP4410N Wireless-N Access Point that I need to set up on to allow wireless users (laptops) to connect to my LAN & access network drives, printers, Internet, etc. I know how to set all this up except the extra laywer of security. I know I can use WPA for security but how can I set up user authenitication? This AP has a feature where it will redirect a user to an internal website for authentication once they connect but I am assuming I need a radious server correct? My question is, what is the easiest radious server to set up? I'll just have less than 5 user accounts. Is this something alinux box can do or some other freeware that will work on a Windows box? I have a active directory domain with Windows 7 computers & iPads. Any advice or suggestions will be appreciated.
