Issue Summary

When users are deleted from a group on the external directory server, the deletion isn't logged to the audit log on syncing to Confluence.
The event was logged on Confluence 8.1 and before, but not logged on 8.2 and after.

Steps to Reproduce

1. Setup Confluence (8.2+) with an external directory server, with 5 minutes sync interval
2. On the directory server, do the following

• Create a user "user1"
• Create a group "group1"
• Add "user1" to "group1"

3. Wait for the directory sync
4. Confirm the "user1" is in "group1" on Confluence
5. On the directory server, delete the "user" from "group1"
6. Wait for the directory sync
7. Confirm the "user1" is not in "group1" on Confluence
8. Check if the deletion event is logged to the audit log

Expected Results

User deletion from the group is logged to the audit log.

Actual Results

User deletion from the group wasn't logged to the audit log.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available.
