Hi! I'm trying to set up a WLAN (5 APs) with a RADIUS Server (SuSe 10.2). RADIUS should authenticate the MAC Adresses of the WLAN Users to grant them access to the network. There are often new computers, which should get access to the Network immediately and without installing anything. RADIUS is running (APs in clients.conf listed, but not yet any further settings made), APs are set up and I can roam in my network all over the office. I use WPA2 PSK at the moment to cipher the WLAN. I have a MySQL Database to enter user information. Question: I just found some options with Certificates/PWs to authenticate users. Can I authenticate them just with their MAC? Where do I specify it in my Database? It's my first RADIUS Project and I don't think I'm a "Stephen Hawking" in RADIUS configuration... ;) Anyway...I'm thankful for every help I get. Thanks in advance Bernd
