Rationale: This patch is meant to enhance user experience in case a client software is used to maintain data directly via LDAP. This is a real-world issue.
Find the patch against master here: https://www.stroeder.com/temp/0001-ITS-8866-slapo-unique-to-return-filter-used-in-diagn.patch Also cleanly applies to RE24 and therefore could be easily added to upcoming release 2.4.47. ;-)
