Upgrading iOS Devices to Mobile Connect 5.0 May Affect SMA 1000 and SMA 100 EPC Policies
The SMA 1000 and SMA 100 series depend on device ID's to apply End Point Control (EPC) policies to end users. Device ID's are generated at the time an end user connects to an SMA appliance using Mobile Connect. Recently Apple has changed security guidelines for third party apps. Apps can no longer pull or use device hardware ID's due to privacy concerns (https://developer.apple.com/reference/uikit/uidevice/1620059-identifierforvendor).
Because of this recent change end users with Mobile Connect 5 may no longer recieve correct EPC policies. Any EPC profile based on equipment ID, device ID, or hardware ID will no longer be able match EPC profiles.
