Apple Push Notification service certificates

To use the built-in Mobile Device Management (MDM) protocol of iOS devices, Sophos Mobile Control must use the Apple Push Notification service (APNs) to trigger the devices.

APNs certificates have a validity period of one year. To notify when the certificate is about to expire, Sophos Mobile Control sends several email reminders to the administrators, starting 30 days prior to the expiry date.

The following sections describe the requirements that must be fulfilled and the steps you must take to get access to the APNs servers with your own client certificate.
