A bunch of tests fail here. The reason is that in `example_directory` (at `okupy/tests/tests.py`) there is no `cn` attribute in the added items. In Gentoo bugzilla `cn` is always set, but even if we add `cn` in `example_directory` items, then the tests will fail later, which means that we need to add every possible attribute in order to succeed. This is wrong, because some of the attributes, eg `gentooIM`, are optional. Thus, you need to fix your code to cover the case where an attribute is not set (and possibly warn the user that one of the important attributes is not set).
