Scenario: Letting the APNs Certificate expire. RRS feed

  • Question

  • Hello

    Recently our APNs Certificate expired, and I could not find any solid answers on what would happen, even after logging a ticket with Microsoft Premier Support.

    Background: We use Office 365, with a separate Intune subscription integrated with SCCM 2012 (Hybrid). The certificate had been expired for twenty days, which prevented devices from enrolling.

    1. I was able to remotely wipe existing enrolled devices, despite the certificate having expired.

    2. All security policies already deployed to existing enrolled devices continued to function (Passcode reset, prevent iCloud backup etc)

    3. I was unable to enrol new iOS devices.

    4. I was unable to update CI policies on existing enrolled devices.

    5. After renewing and uploading the certificate, ALL THE PREVIOUSLY ENROLLED DEVICES CONTINUED TO WORK. That is to say, I did not need to re-enrol all 700 devices. This will work provided you use the SAME APPLE ID TO RENEW THE CERTIFICATE!

  • Ultimately, this is a question for Apple. The APN cert is the "key" to accessing the Apple Push Notification (APN) network as well as the devices connected to them and really has nothing to do with Intune. Intune uses the cert for sure but they (Apple) define the behavior of what happens when the cert is expired or replaced.

    What you've stated above goes against what I've been told, but I've never explicitly tested either and am not an APN guru by any means. Number 1 seems to make sense though as that's one thing you probably want/need to do if retiring an MDM. The rest also makes sense if the cert was issued by the same account. This may be a change also from previous behavior. As noted though, this is a much better question for Apple though.

  • Have you ever tried to get an answer out of Apple that isn't 'backup your data and restore your iPhone'?
