I know this is a long post but please bear with me:
I have an iPad Mini (A1429) / 7.0.6 which has been wiped, and set up as supervised and locked to my individual laptop with Apple Configurator 1.4.3
I have a custom app (enterprise licence) that the iPad is locked into using the supervise pane in Configurator.
Now, according to the documentation I've read, supervised devices automatically disable the ability for activation-lock to be used by the end-user of the iPad (I'm assuming to prevent disgruntled employees locking iOS devices with personal apple IDs).
My assumption is that because of the activation-lock prevention, supervised mode should prevent the iPad from synchronising with any other computer - especially if the device is stolen, so I tested this theory...
I plugged the iPad into another computer running iTunes. 'This device is supervised by another computer'. Working as expected.
So I placed the device into recovery mode, then plugged it into iTunes, which detected an iPad in recovery mode. I proceeded to restore the iPad, and it got half-way through the process before realising it was supervised, and bounced me back into the locked app. This worked as expected too.
Then I placed the device into recovery mode a second time, plugged it into iTunes which detected an iPad in recovery mode, and then tried to restore the iPad a second time.
Then something happened I didn't expect. The restore worked. And it presented me with the welcome screen. And it didn't present me with any activation-lock particulars. I was left with a pristine restored iPad free of all restrictions, pass-codes and activation locks.
My question to you all: IS THIS A BUG? or is this standard behaviour that is allowed by apple? Because I would assume that there are supervised devices out there that admins don't want wiped by another computer.
