Hi,
I´ll like to know if there is a way to configurates a Radius server + Mysql to authenticate Wireless clients via a Cisco AP without certificates (EAP TLS), only a username and password
yes. we use Cisco APs - we used to use them in autonomous mode but moved to the lightweight LWAPP (now CAPWAP) mode a few years back. I would not recommend broken captive portals. 802.1X is the way forward (and is now beign mandated by several government and education procurement systems around the world - expect any half-decent auditor to pick up on this too. for EAP, you can use EAP-PEAP or EAP-TTLS - in which your RADIUS server has a certificate signed by a CA. the clients dont need certificates, they just need to have the CA on them that signed the RADIUS server (for trust!) alan
