Install And Configure OpenLDAP On Ubuntu Karmic Koala

The configuration of OpenLDAP got a bit (more) complicated. cn=config is still used, but when installing the packages from the repositories only a skeleton configuration of openldap is installed.

You will have to set up the openldap database, root dn and acl's yourself using the root account (or sudo) in order to configure openldap.
