slapd manages indices during ADD/DELETE/MODIFY/MODRDN operations.
Older versions of slapd did not do index removal.  Some changes
where made in 1.2.4 and subsequent to do index removal.  We
generally recommend all users update to the latest "stable"
release, currently 1.2.6.

As the efficent of indices decreases as they age, you should
rebuilding indices on a regular basis (depending upon the
amount of modification your directory experiences).   In addition,
you should rebuild your indices after removing a large percentage
of your directory.
