While you're at it. why not upgrade your OpenLDAP version to 2.3 (2.3.34
is the latest version, though 2.3.32 is classed as "stable"). This will
do your db_recover automatically, though you shouldn't be getting this
problem with a properly built db and up-to-date bdb libraries. 2.3.32/4
has a number (like tons) of significant improvements over previous minors.
