        1. Create a test_user
        2. Create a test_group and make test_user member of test_group
        3. Disable memberof plugin, so that when test_user is deleted, test_group is not updated
        4. Break the 'member' index, making it ignore 'eq'
        5. remove test_user. test group is not updated and member: =<test_user>.dn --> test_group.entryId remains
        6. reenable 'eq' for member index
        7. Enable Referential integrity
        8. Enable filter logging (error log)
        9. delete test_user -> referint will search 'member=<test_user>.dn' and will Bypass the filter
