I have cinfugured 802.1X with the following componentes
- Windows Server 2003 AD with enterprise CA
- Cisco Secure ACS 4.2 like Server AAA, Setup to use EAP-TLS authentication with Machine Authentication.
- Win XP SP3
I tried to authenticate the machine with Win XP SP3 using EAP-TLS but sometimes the ACS Server doesn't receive the request and other times the authentication fail.
I need implement EAP-TLS to force to use it certificates but the client uses only Windows XP SP3.
What is the problem to use EAP-TLS with Win XP SP3?. I used Windows and it works almost fine but there is one problem: the user is asigned to the default group and not to the group mapped..
