Close, except for the version references. OpenLDAP 2.0 only provided
back-ldbm, which has no notion of db_recover at all. Early releases of
OpenLDAP 2.1 did an automatic recover on back-bdb, and that was later
disabled to prevent inadvertently destroying the BDB environment when
multiple slap binaries were executed.
