Adding iOS 11 devices to DEP using Apple Configurator Until now, only iOS devices purchased direct from an Apple sales channel could be added to the Device Enrollment Program (DEP). But at WWDC June 2017, Apple announced that any device running iOS 11 or tvOS 11 could be added to DEP. (The information is in this presentation - p25 of the PDF or around 05:20 in the video.) Although it wasn't stated explicitly, the slide implies that this requires Apple Configurator 2.5.

Is this functionality implemented yet in the beta releases of iOS 11/Apple Configurator 2.5? And if so, how do I use it?

What I've tried/found so far:


I've got a couple of devices (iPhone 5s, iPhone 6 Plus) running the current iOS 11 beta (build 15A5278f, 5 Jun 17) and a Mac running the current Apple Configurator 2.5 beta (build 3F12, 5 Jun 17) but I can't find a way to add either device to DEP.
If I connect an iOS 10 device to the Configurator I get exactly the same options (which indicates there's no special support for iOS 11 yet).
In the Prepare Devices screen there is an option Add to Device Enrollment Program which is disabled and can't be enabled:
In the new beta 2.5 it's active but when you are on the step where you need to login to your DEP account I get an authentication error. I'm 100% sure I entered the right credentials: even used 2 DEP accounts and still not working.
