am using cisco ACS SE to authenticate users on my wireless lan from the microsoft AD,my clients are using XP and so am using PEAP as my authentication protocol.
when i try to log on to the network from my laptop i get the following error from the ACS SE log.how do i solve this problem and what is causing it?.
EAP-TLS or PEAP authentication failed during SSL handshake
Please uncheck "Validate Server Certificate" on the client's peap settings
Install the root certificate of the CA which signed ACS's certificate on the client.
