Description (partial)

For ISE with BYOD provisioning for EAP-TLS the scep proxy process will fail for the following scenario:

ISE using identity certificate for EAP - that is signed by CA1
ISE using scep proxy signed by different CA (CA2)
ISE is trusting both CA1 and CA2.
Windows7 supplicant does not trust anybody - we want to make onboarding and trust both CA1 and CA2. When using Network Setup Assistant on supplicant it will fail with error:

[HTTPConnection] InternetOpen() failed with code: [12045]

(because it has accepted only CA1 while scep session is signed by CA2).

On ISE we will see that scep proxy has been terminated by supplicant:

        at org.jscep.transport.AsyncGetTransport.sendRequest(

For Apple Ipad we do not have that problem, Ipad accepts both CA's (each needs to be confirmed) and put correctly into profile.

ISE BYOD with scep-proxy signed by different CA then EAP ISE certificate. Problem occurs only for windows, Ipad works fine.
