OpenLDAP Faq-O-Matic: How do I install OpenLDAP?  You follow the
instructions in the INSTALL document found in the release.
What’s great about OSS projects is that you can answer questions
like this in just such a manner and not worry about it. Closed
source, retail products have to play by the “no question is a
stupid question rules” or run risk of losing customers.  Of
course, in the land of Windows, double-clicking a setup.exe or
install.msi is not exactly something that requires an “How do I
install this?” FAQ.  Then again, anyone who has worked in
customer support knows that this generalization is just that… A
generalization. ;) [insert “Sir, is your computer plugged in?”
customer support line story here.]
