I am having kinda the same issue, although it is similar to the peap issue thread.
We use peap with CiscoSecure ACS.
In the CiscoSecure ACS Failed Attempts Reports I am getting this message
'EAP-TLS or PEAP authentication failed during SSL handshake'
From what i have found this is saying the certificate the bb is using is invalid.
Following the instructions from the bb manual...
I copy the certificate off the acs server and install it on my computer.
I startup Certificate Sync and the certificate is showing up under 'Others People's Certificate'.
I checked it and synched. In the bb wifi setup going through the lists of certificates I can not find my acs server cert anywhere. I tried using the intermediate cert Thawte SGC CA it doesn't work.
I dont know why my acs server cert is not displaying on the bb. Certificate Sync is showing its installed. It did install the intermediate cert that i tried above during the same synch.
On the bb in the wifi diagnostics i am getting a 'Network deauthenicated client' message.
i also tried selecting the Class 3 Public Primary cert which is what we set the laptops to and that doesn't work either.
Any help would be appreciated.
