code: public static Entry namedDescriptiveObject(Dn dn, String... descriptions) {
          Entry entry = namedObject(dn);
          addDescriptions(entry, descriptions);
          return entry;
      }
docs: Returns an {@link Entry} having the given {@link Dn}. The attribute type of the Rdn is 'common name'. The
  description is optional in that it may also be null or the empty String. Callers can rely on this distinction,
  i.e. storing an empty string will also retrieve an empty string and storing null will also retrieve null.
