My OpenLDAP Online Configuration (OLC) Reference provides the OLC equivalents of the configuration file options. It should be pretty accurate as I read the source code to determine which OLC attributes correspond to the configuration file options.
For a description of what the various options do, consult the appropriate man page or the official Administrator’s Guide .
If you know the object class the option applies to, you can jump to it on the page by selecting it from this menu and clicking the “Go” button:
