Yeah, stop the presses right here -- the problem isn't fixable by
caching queries, it's fixed by properly configuring (the backend,
indexes, etc.) OpenLDAP to improve its performance. It'll blow the
doors off of NDS, so if you're seeing slow-downs, it's your
configuration, not the software. Don't add a layer of dumb (caching) in
an attempt to fix this.
Besides, what's "*a lot*" mean?
