UDM can not find dns/host_records if not at least one of the attributes 'aRecord', 'aAAARecord', or 'mXRecord' is set. root@master10:~# univention-ldapsearch relativeDomainName=some_host # some_host, foo.bar, ucs.dev dn: relativeDomainName=some_host,zoneName=foo.bar,dc=ucs,dc=dev objectClass: top objectClass: dNSZone objectClass: univentionObject univentionObjectType: dns/host_record relativeDomainName: some_host dNSTTL: 10800 zoneName: foo.bar root@master10:~# udm dns/host_record list --superordinate zoneName=foo.bar,dc=ucs,dc=dev (no result) This is caused by a broken identify() function in the dns/host_record.py module, where at least one of the attributes 'aRecord', 'aAAARecord', or 'mXRecord' is expected, otherwise the object will not be classified as dns/host_record.
