To secure your MDM communication you need a certificate issued to the domain where the MDM server resides. In the case that there is no certificate associated with the domain where the MDM server a Certificate request to a trusted certificate authority provider should be initiated before proceeding. As this can take some time, this should be done in due time before implementing MDM in your system.

New Apple Push Certificate Service

| Info |

In order to communicate with Apple devices, CapaInstaller relies on the Apple Push Notification service (APNs). The APNs requires that each service identifies itself by using a certificate issued by Apple, ensuring that only authorized services can contact Apple devices. Before an APNs certificate can be issued using the Apple Push Certificate Portal, a certificate request must be generated and signed by an authorized MDM vendor, in this case, CapaSystems A/S. To upload the certificate request to Apple, an Apple ID is required. It is strongly recommended that a unique Apple ID is created for this purpose, DO NOT use your personal Apple ID for this. |
