The entry specified by dn is renamed/moved. The new RDN is specified by newrdn and the new parent/superior entry is specified by newparent. If the parameter deleteoldrdn is TRUE the old RDN value(s) is removed, else the old RDN value(s) is retained as non-distinguished values of the entry. 如果成功则返回 TRUE，失败则返回 FALSE。
