Thanks Kerry. I just updated this post with the link to the real article. Previously I had linked in a draft.

Just to clarify, the official documentation you mention is focused on customers who are installing Sametime Standard with the full set of features including meeting and A/V capabilities, using LDAP directories and DB2. The scenario in this article talks about installing Sametime Entry with a Domino directory for use in organizations that don't need online meetings or access to the larger feature set of Sametime Standard 8.5.x. We'll put a note in the regular information center the next time we update it to point to this article. Thanks for providing this information to the community.
