Environment
Mobile Management (ZENworks Mobile Management)
Situation
Beginning on March 31, 2021, Apple is making changes to the
APN (Apple Push Notification) process that iOS devices use for
communication with MDM servers. To prevent issues with the
standalone ZENworks Mobile Management (ZMM) 3.2.x environment,
there is a patch that must be applied for APN communication to
continue working.
If the patch is not applied, iOS devices will no longer be
able to sync with the MDM server and will not receive policy
updates or security commands after this time. With the patch,
this functionality will work until December 31, 2021, at which time
ZMM will no longer support iOS management. Therefore all
users should be moved from ZMM to ZCM prior to that date.
Resolution
For customers still using ZMM between March 31st, 2021 and
December 31st, 2021, you will need to apply a patch to your ZMM
server to allow continued communication.
The patch can be downloaded from https://download.novell.com/Download?buildid=uwfM4emJKB8~
The patch contains dll files that need placed in two
directories. The process would be as follows:
- Stop the World Wide Web Publishing Service.
- Either rename, or move the existing dll files to another folder.
- The files in the dll folder are placed in C:\Program Files (x86)\Novell\ZENworks\mobile
- The files in the 'extension dll' folder are placed in C:\Program Files (x86)\Novell\ZENworks\mobile\php\ext
- Start the World Wide Web Publishing Service.
Once this is complete, confirm that APN commands are still
communicating with your iOS devices. The easiest test would
be to ensure an iOS device is unlocked and then send a lock command
from within the ZMM Dashboard.
