The delete setting is enabled, but the systems are not deleting from the tree
As Hem suggested above option is already selected and if still it is not deleting system from the system tree it seem like the issue is related to article
KB78932 as you have mentioned. Because as per the configuaration ADSync task should delete those machines which are not present in the AD OU. So you can refer the same article and apply the workaround to delete those machines manually from the system tree or you can apply patch 1 for ePO 5.0.
Please refer article : https://kc.mcafee.com/corporate/index?page=content&id=KB78214
Issue: The System Description is updated by AD Sync tasks and then overwritten at the next agent to server communication with local computer descriptions.
Resolution: This issue is not listed in the Resolved Issues section for the ePO 5.0.1 Release Notes. However, it is resolved in ePO 5.0.1.
Just wait for ePO 5.0.1
No need to wait, it is available from the corporate download portal.
Thats only the BETA version?
5.0.1 is patch1 for ePO 5.0 which is available for download. ePO 5.1.0 is in Beta release.
Hang on - can you explain in a bit more detail what's happening? From what you describe I think this is normal...
The AD sync only applies to the group(s) where the synchronisation is defined - so if I have a group called A with a sync point defined, and I move a machine from group A to group B and then delete it from AD, it will *not* be deleted from group B.
You are right, the ADSync only applies to the groups where the synchronisation is defined so if you have a group called "A" which is a sync point defined and you move some machines from group "A" to group "B" . It means the machines has moved from group "A" to grop "B" and those machines are not present currently in group "A" but you have defined group "A" as synchronisation point, so whenever ADSync task runs it should resconstruct the system tree according AD and whichever machines are deleted or moved from the group "A" those machines should not be present in ePO system tree under goup "A".
