Hi Jasvinder,
iPhone configurator has been indeed deprecated some while ago. It sort half worked in iOS 7, and it finally stopped being useful in iOS 8. At the moment, only XCode is useful for that. Apple configurator is used in a corporate setting, however last time I checked, it was only supported in a handful of countries, and not here in Portugal. Someone more used to it can comment.
As for the profiles, we are generating them with
cat.eduroam.org, because we are a university. However you also have available the service for free at
https://802.1x-config.org for a corporate setting.
Nevertheless, the profiles are essentially text files. So after generating the first, you can keep it. I also believe you can download client certificates never tried it. You just have to be aware that to download profiles or certificates you have to use the native Safari and not other browser.
I also wrote a tutorial to the Portuguese federation on implementing FR 2+EAP-TTLS+AD, that I will have to update to FR 3 and make a little more presentable to distribute it widely.
Feel free to contact me if you need more ideas about the Apple profiles.
Regards,
Rui Ribeiro
