Yeah, backend specific settings go in the backend specific man pages.

I just added that option to Stanford's OpenLDAP servers last week, so I

As long as you have enough RAM, I don't think so.

Howard gave me a general rule of thumb:

For BDB, idlcachesize should be equal to cachesize in slapd.conf

For HDB, idlcachesize should be 3 times cachesize in slapd.conf.

I'll put that in my page too. ;)
