Thu, 27 Jun 2024 20:53:03 -0000

Using latest samba 4.20.2 from Debian Trixie repositories, the latest
bind9 upgrade to version 9.19.24 fails to start on DC's using dlz_bind.?
Reverting back to bind9 9.19.21 restores full functionality.? On
standalone systems running the same samba version with the latest bind9,
named starts with no issues.

The most recent dlz_bind version available is dlz_bind9_18.so. Since the
kernel is mentioned in the error, that version is linux-image-6.8.12-amd64.

The syslog error message is shown below.? Has anyone else experienced this?
