Yes. Refer to the documentation on slapd.conf. When you add the index
you will have to dump your database to an ldif file so that you can
generate the index. I've previously posted to this list the procedure
for how to do this, and you may also find information about it in the
FAQ-O-MATIC. Alternatively, you could add the index and reload the
entire database, which shouldn't take long for only 40,000 entries.
You should probably have at least presence and equality indexes.
