OpenLDAP - where is my slapd.conf?

I have installed OpenLDAP on Unbuntu 10.04.
I wanted to configure my ldap but I can't find slapd.conf in /etc/ldap/
In this directory there is a ldap.conf but seems not to be the same.

How can I configure my ldap ?

You will need to use the new cn=config configuration method, where the LDAP server will be configured via a separate data tree in the directory (which is usually represented as LDIF files under /etc/ldap/slapd.d.

OpenLDAP uses a separate directory which contains the cn=config Directory Information Tree (DIT) (formerly slapd.conf). The cn=config DIT is used to dynamically configure the slapd daemon, allowing the modification of schema definitions, indexes, ACLs, etc without stopping the service.
