This is true of version 2.2. But the syncrepl provider code for the 2.3
release has be completely rewritten as an overlay. That can also be
used with other backends. From the 2.3 admin guide
"... The syncrepl engine, which is a consumer-side replication engine,
can work with any backends. The LDAP Sync provider can be configured as
an overlay on any backend, but works best with the back-bdb or back-hdb
backend. The provider can not support refreshAndPersist mode on
back-ldbm due to limits in that backend's locking architecture. ..."
