That's also expected, since hasSubordinates is a dynamically generated operational attribute (and also read-only, as I recall). You need to exclude any dynamically generated operational attributes from the syncrepl search. E.g. 2.4's test045 specifically tests this scenario, and the syncrepl spec uses: syncrepl rid=1 provider=ldap://localhost:9011/ binddn="cn=Manager,dc=example,dc=com" bindmethod=simple credentials=secret searchbase="dc=example,dc=com" filter="(objectClass=*)" attrs="*,structuralObjectClass,entryUUID,entryCSN,creatorsName,createTimestamp,modifiersName,modifyTimestamp" schemachecking=off scope=sub type=refreshAndPersist retry="5 5 300 5" In general, while this is known to work in 2.3, you're better off using 2.4.
