Unable to delete domain

[Eloy]

Hi

I would like to delete a domain from Kolab, but I am unable to do so.
This is the output of the command `kolab delete-domain [domain]`

Do you have any idea how to solve this?

Traceback (most recent call last):
  File "/usr/sbin/kolab", line 39, in <module>
    kolab = Cli()
  File "/usr/lib/python2.7/dist-packages/pykolab/cli/__init__.py", line

    commands.execute('_'.join(to_execute))

    return response_data

Thanks in advance,
