Hi,
before buy a new public certificate, I tried to set group policy in the active directory domain but unfortunately it doesn't work. We configure a wireless network with WPA2 Enterprise - AES, authentication method: Microsoft PEAP with authentication user or computer and unccheck "validate server certificate" but when I try to connect on clear-pass authentication was rejected with alerts:
"EAP-PEAP: fatal alert by client - unknown_ca eap-tls: Error in establishing TLS session".
Did I miss something? I have to add CPPM certificate on wireless configuration?
Until now we use termination on the controller, but default certificate is expired on 08/11/2017 and, so we would pass authentication directly on CPPM.
As I can't use wildcard certificate on CPPM I created a Self Signed Certificate
Thanks for you help
Best Regards
