the dhcpd instance does a query against ldap, trying to find an object
with the dhcpServer object class, AND a common name of wso2.  either of
these may exist in your environment, but BOTH conditions must be
fulfilled.  when an object with BOTH conditions is found, it must have
the attibute of dhcpServiceDN, and the value of that attribute must
point to the location in the directory that contains the configuration
information for the dhcpd instance.
