All the unknown heirs of deceased persons and all the unknown persons or parties served by publication as provided in AS 09.45.920 have the same rights as are provided by law in the case of all other defendants upon whom service is made by publication, and the action shall proceed against the unknown heirs or unknown persons or parties in the same manner as against defendants who are named and upon whom service is made by publication, and with the same effect. The unknown heirs or unknown persons or parties who have or claim an interest, right, estate, or lien in the said real property in controversy at the time of the commencement of the action and who are served as aforesaid shall be bound and concluded by the judgment or decree in the action as effectually as if the action was brought against the defendant by name and constructive service of summons obtained.
