Description Felix Botner

+++ This bug was initially created as a clone of Bug #43846 +++

Trying to uninstall Docker App "Dudle" on a Domaincontroller-Master which is joined into AD.

Domaincontroller-Master was freshly installed from 4.1-4 ISO, immediately joined into AD domain.

Then installed Docker App "Dudle". The fake hostname 'dudle-<digits>' was synced into DNS of AD, even with the unreachable 172.17.x.x address.

Trying to uninstall the Docker App fails with message:

File "/usr/lib/pymodules/python2.7/univention/appcenter/actions/register.py", line 294, in _unregister_host
    remove_object_if_exists('computers/%s' % app.docker_server_role, lo, pos, hostdn)

invalidOperation: Objects from Active Directory can not be removed.

Should there be an exception to the above rule, or is it wrong that the host entry was written into AD at all?
