using SSL certs with EAP-TLS

I also sent Matthieu an email offlist.

After reading
http://community.arubanetworks.com/t5/AAA-NAC-Guest-Access-BYOD/iOS-quot-not-verified-quot-for-trusted-certificate/td-p/228121
and https://discussions.apple.com/thread/5967450 I'm beginning to think:
it can't be done, no warning on iOS. One will always get a certificate not
verified warning upon the first connect in iOS. iOS's brother OS X is not
complaining.
