Hi All, I'm trying to get am MacOS 10.5 client to connect to a cisco 1250 ap running IOS 12.4(10b) authenticating against Freeradius 1.1.7 on Ubuntu (8.04). Yeh md5 is a bad idea, but it should be a simple first step. The only changes I made to the default Freeradius config were to add the client info for the 1250 and one user: jon Cleartext-Password := "password" Freeradius sends: Sending Access-Accept of id 56 to 192.168.32.10 port 1645 EAP-Message = 0x03020004 Message-Authenticator = 0x00000000000000000000000000000000 User-Name = "jon" Finished request 95 Which the AP sees: *Mar 1 17:13:08.871: RADIUS: Received from id 1645/54 192.168.32.34:1812, Access-Accept, len 49 *Mar 1 17:13:08.871: RADIUS: authenticator 80 F5 FE FA 84 E9 7A EB - C9 D0 0C F2 E5 07 9C 02 *Mar 1 17:13:08.871: RADIUS: EAP-Message [79] 6 *Mar 1 17:13:08.871: RADIUS: 03 02 00 04 [????] *Mar 1 17:13:08.871: RADIUS: Message-Authenticato[80] 18 *Mar 1 17:13:08.871: RADIUS: 61 20 78 47 53 68 E0 80 20 7F 10 04 95 CE 64 9D [a xGSh?? ?????d?] *Mar 1 17:13:08.871: RADIUS: User-Name [1] 5 "jon" *Mar 1 17:13:08.871: RADIUS(000000B0): Received from id 1645/54 *Mar 1 17:13:08.871: RADIUS/DECODE: EAP-Message fragments, 4, total 4 bytes *Mar 1 17:13:09.919: %DOT11-7-AUTH_FAILED: Station 001e.c2b7.f0de Authentication failed But note the AUTH_FAILED at the. The Mac client then just spins retrying athentication. I must be missing something so stupidly obvious noone else has ever missed it, as I can't seem to find anyone onlline who's had trouble with simple md5 auth... Help? Thanks, -Jon
