I am presently deploying in a Campus network of 2 WiSM's with 280 1250 AP's .
Authentication is carried by means of ACS appliance,1113. I have generated a certificate and installed on the appliance itself.
Now the problem lies, when a client tries to authenticate ,it stucks with Validating identity, but when I manually install the certificate from ACS to the client machine , it works but gives disconnection after sometime.
Any ideas / advises.
