    Mapped Groups don't exist breaks WebSSO

    The issue occurs if a user has a group that
    does not map to a project in OpenStack. At
    which point an exception is raised and the
    websso login blows up with a 500 message.
    This is because of the exception being raised
    when the group name not matches thus replacing
    that with a log.
