I went through the whole process, created rpm packages, created docker image, tested the
rpm packages installation on the VM, same behaviour, same DEBUG message "... DEBUG
Not updating schema". Tested the docker image on another VM with podman, same
behaviour. So to answer my own question, the plugin approach is not doing anything more
than the manual approach.
I'm pretty much on the verge to give up on FreeIpa and switch to a simple openLDAP,
this is getting out of control.
