Restoring with SLAPADD

OpenLDAP 2.3.40 and 2.4.7.

Testing disaster recovery, such as a bulk update gone wrong, so need to restore from last night's "slapcat" dump (we hardly ever write to the directory, so it's no big deal losing a morning's work).

Delete an entry. Oops, I need it back. Stop the master (and slave), "rm *.bdb __*", "slapadd -nX < slap.out", start the master and slave, check the slave, and the deleted entry has reappeared.

Is this guaranteed behaviour i.e. the slave will always resynchronise in this case, or was I just lucky?

If it makes a difference, we use SyncRepl in "refreshAndPersist" mode.
