He did not indicate which ports he needed to have open and on which side the needed to be open to.
For example, 80 and 443 need to be open to the internet to allow external host to use OWA. "The others" need to be open between the DMZ and internal lan to allow the FE server to do GC looksups, etc.... Sorry for the confusion.

There are MANY more that are required to be opened to allow for communication between the FE server and the BE server, and communication betweent the FE server and the DC/GC servers. While the article seems to point out the correct ports, the post was misleading in saying that only 80/443 and a "few others". Those "few" other ports (esp. 135, and the LDAP ports) are something I would not especially want opened on my firewall.

I agree that putting a Front End in a DMZ is no walk in the park and did not intend to make it sound that easy.
