    Hi Michael, 

    Thanks for the note! Our knowledgebase is living and where there are issues we count on our engineers and users to highlight them!

    In this case, the article really is no longer relevant given some significant changes since it was written. 

    I'm going to remove it to avoid further confusion and open a case for you as presumably you're looking for something specific.
