Hi, We are building freeradius server to authenticate WLAN users with EAP-TLS and EAP-PEAP. EAP-PEAP works great with all tested operating systems, but Mac OS X 802.1X client with EAP-TLS kills freeradius if check_cert_cn is set on and Mac OS X user sends user name which does not match with certificate's common name. Operating system version is 10.4.8 and it runs on Macbook. If Window XP user sets different outer identity than cert's common name freeradius works ok (user gets rejected). We have tested following freeradius server versions on following platforms Freeradius 1.1.1 / SUN Os 5.8 Freeradius 1.1.3 (FC6's rpm) / FC6 Freeradius 1.1.4 (build from source)/ FC6 Freeradius snapshot 20070118 (build from source) / FC6 Freeradius 1.1.4 (build from source) / CentOS 4.4 FC and Centos are using distros default openssl libs etc. Heres some log and debug from CentOS with freerad 1.1.4 http://cc.oulu.fi/~mraisane/tmp/radiusd.txt Any ideas, fixes or workarounds?
