It is always a good thing to ask questions, but in this case, you asked
the wrong question ;-)

You should have asked 'am I reading the right documentation', and I am
sorry to say, you were not. Some of the document you referred to is
still valid, but a lot isn't. The first point of call for Samba
documentation is the Samba wiki and the various manpages that Samba
supplies.
The document, that you referred to, will not be updated, it is just
supplied for historic reasons.
