I am trying to set up icingaweb2 with LDAP authentication talking to a local icinga2 setup via command pipe. After running the setup wizard I can successfully log into icingaweb2 but I am getting the following error message both in the Web UI and logs:

My goal is to update a non-interactive setup script for Debian bullseye (see share/debian-edu-config/tools/edu-icinga-setup · personal/gber/icingaweb-fix · Debian Edu / debian-edu-config · GitLab).
I am using Debian bullseye which provides icinga 2.13.6 and icingaweb2 2.11.4 packages running on PHP 8.2 under Apache with MySQL and OpenLDAP.
