The new OpenLDAP configuration is an LDAP tree like any other, and can be browsed as such. Using a graphical browser like Apache Directory Studio can simplify configuration (somewhat).
When setting up a new LDAP connection, specify the user as the admin user for the configuration tree – like so:
cn=admin,cn=config
Also specify the tree root as:
cn=config
With the appropriate settings, you should then get a list of the configuration tree, where you can view and edit entries. It would behoove you to be very careful about changing things in this tree: if you change the wrong thing, your LDAP server could stop functioning properly.
