Initial contents for the LDAP database, in LDIF format.

This differs from <code>declarativeContents</code> in that this will
only be used to create the database if it doesn't exist, not replace
the contents each startup.

Cannot be used alongside <code>declarativeContents</code>, as that
would completely override this option.
