Short description

While "debugging" a few things in a new installation with tinydns backend (one single cdb file) I noticed that I'm unable to send notify to secondaries. If I try to force it via pdns_control notify I get No such domain xxx in our database, despite pdns_control list-zones being flawless All zonecount: 40. Meanwhile pdns answers all queries flawlessly.

So, I launched pdnsutil check-all-zones and I discovered that for every zone I get: [Error] Unable to get zone information for zone 'xxx' Also, for every zone after the first I get: [Error] Zone ID 4294967295 of 'xxx' in backend tinydns has already been used by zone 'firstzone' in backend tinydns. This is consistent with pdns assigning a default id to all tinydns zones but I wonder if it's part of the problem.

Environment

• Operating system: Gentoo linux kernel 6.6.30
• Software version: 4.9.1
• Software source: Gentoo packages

Steps to reproduce

1. Configure pdns to run with a tinydns cdb backend (with more than one zone?)
2. Try pdns_control notify for any zone, it fails for me Config, comments removed:
