hi all, I wanted to make an AP with MD5 eap auths on the linux kernel 2.4.20,hostapd 0.4.2,madwifi 20050629,chip 5212.I have execessed in the wpa-psk mode.But when I tried the MD5 and Radius,the user can't pass the authorization.I didn't know where is the mistake.I hoped to find the same cases in the internet,but nothing found. I hope some one can help me,any suggestion will be greatly appreicated here is the DEBUG message: IEEE 802.1X: 5 bytes from 00:0c:41:c2:2f:7a IEEE 802.1X: version=1 type=1 length=0 ignoring 1 extra
