Hello,
I'm in the middle of testing a deployment of dot1x. It works fine for my windows clients, but when I tried to authenticate a polycom phone, I was getting the following message:
EAP-TLS: fatal alert by client - unknown_ca TLS Handshake failed in SSL_read with error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca eap-tls: Error in establishing TLS session |
I confirmed that the certificate it has is trusted by the CA. I the thumbprint and serial number match and I can see it's trusted when I import the cert anywhere else. Any suggestions on where to check into this?
