Been playing around with this for a couple of days. Very impressed so far, considering this is only an alpha release. I'm not sure whether this has been fully implemented yet, but I tried to create a new user in "pdm" realm to avoid using root user. Creating the user works great, however I cannot seem to assign permissions to this user, so even though I can log on, I am getting all sorts of errors as the user is not authorised to do anything.
