can be an hdb root?

[Christ Schlacta]

can I create an hdb root of ?  I would like to set up a server for testing,
and i'm wondering if I can configure my server such that the root is
essentially "", or "Empty String", so that I can add dc=testing,dc=com, or I
can add ou=test1,...testn, or I can add anything else I want for
experimenting with and learning how many features of openldap work, without
having to constantly reconfigure my root, or be trapped in one awkwardly
long root.
