GroupWise Mobility Service security and iOS 13 and macOS 10.15

In mid-September 2019, Apple will be releasing iOS 13 on all new devices.  They are changing the way that these devices handle TLS and certificates.  These new requirements will have an effect on all devices using GMS.

This is a change from Apple and we cannot change it.  Please review this document Requirements for trusted certificates in iOS 13 and macOS 10.15.  Make sure that the certificates on new devices meet these requirements
