Rectifying includes adding records for empty non-terminals in the appropriate places, so that a proper empty NOERROR (aka NODATA) is returned if there are child records. After editing a zone, a rectify is needd. When using the API that is taken care of by default (on a reasoably modern version). But not if you edit the DB by hand. -Otto _______________________________________________ Pdns-users mailing list [email protected] https://mailman.powerdns.com/mailman/listinfo/pdns-users
