As I've said, I have horde (dev6) working on Opensuse 15.4 and php  
8.0. I also did a force upgrade to php 8.1 and Horde continued to  
function just fine on Opensuse 15.4. Try to install at least one  
component, preferably Imp and see if that installs other modules that  
you might be missing.

Do:

$  composer require horde/imp dev-FRAMEWORK_6_0

When I go to your site like this:

https://horde.grubit.at/horde/login.php

I'm getting an Auth driver not found. This is because there is no  
cookie being set for Horde_Auth. I'm a little unclear why that would  
happen, offhand. I see Net_DNS2 is also missing, but that will be  
installed if you add the "imp" package.

Going to your site:

https://horde.grubit.at

...without a trailing path, it is redirecting without the  
hostname...somehow it is NULL. I've tried all manner of weird things  
on my OpenSUSE installation to try to get the system to NOT return the  
hostname and I can't seem to reproduce that odd behavior.

Thanks!
