We have a few people that get an error saying "The identity of the authentication server could not be established" when trying to connect to an 802.1x network (Extreme IdentiFi running 9.21.003.0010) on 3825i. NAC reports this for the user:
TLS Alert read
close notify TLS_accept: failed in SSLv3 read client certificate A error:140940E5:SSL routines:SSL3_READ_BYTES:ssl handshake failure
Any ideas? It's not everyone, just a small subset of people.
