Symptoms

Deleted users in AD is not deleted on Confluence side when incremental synchronization run successfully. This changes only reflected on Confluence when full synchronization ran successfully.

Steps to Reproduce

1. Integrate Confluence using connector method against active directory server
2. Make sure "Incremental Syncronization" is enabled
3. Synchronize the newly created directory
4. Create a test user on your active directory server
5. Synchronize the newly created directory
6. Ensure that the users retrieved by Confluence
7. Delete the user from your active directory server
8. Trigger the synchronization and wait till it ran successfully
9. After synchronization finished, Confluence did not delete the deleted user

Expected Behavior

Confluence should delete the user without the need to disabled incremental synchronization. This issue is not reproducible in Confluence 5.1.
