Hi, Welcome to LQ.
It's always helpful for other folks if they know the answers to some of the questions like:
What platform are you on?
What version of the program (1.x, 2.x, etc.). are you running?
What was your install command (using a package manager like yum, or did you install from source)?
I see you have windows 7 in your icons, but you may not be asking about that.
Red Hat / Fedora: /etc/openldap/slapd.conf
Ubuntu / Debian: /etc/ldap/slapd.conf
(Ubuntu 6.06) See example: /usr/share/slapd.slapd.conf)
/etc/default/slapd - (Ubuntu) Defaults should be ok.

Hope this helps, or at least you can get back to us with more info that is often necessary to help!
Also, remember, it's a good idea to read the stickies, and introduce yourself and familiarize yourself with the community by reading other posts to see examples of how they're asked and responded to.
