I have ACS 4.2, I can't get it to authenticate my wireless clients. I am still getting EAP-TLS/EAP fail during HANDSHAKE. I triple checked my cert at both end and everything under advance setting tab is all good. I can use the same server to login to my cisco routers,switches and even the APs. I need to open a case with cisco TAC. What information from the ACS SERVER i need to open the case?
