Program: Authoritative
Issue type: Bug report

Short description

Shorthand AAAA records using the LDAP backend in strict mode don't create PTR records, while fullsize AAAA records do.

Environment

Operating system: Linux
Software version: 49
Software source: https://hub.docker.com/r/powerdns/pdns-auth-49

Steps to reproduce

Set up a ldap backend according to https://doc.powerdns.com/authoritative/backends/ldap.html
Set ldap-mode to strict
Create a SOA for a ip6.arpa record
Create a entry with a shorthand ipv6 dns record, ie 1:2::3, notice that PTR records don't resolve
Expand to 1:2:0:0:0:0:0:3, notice that PTR records now resolve

Expected behaviour

Shorthand ipv6 AAAA records should register PTR records the same way as full size ipv6 addresses.

Actual behaviour

Shorthand ipv6 AAAA records don't register corresponding PTR records.

this is documented at https://doc.powerdns.com/authoritative/backends/ldap.html#ipv6-reverse-lookup-doesn-t-work-in-strict-mode, and is unlikely to see improvement any time soon
