My dayjob is as a business process consultant, specialising in the Atlassian application stack among other things. Almost every single hour of my time working with an enterprise customer involves dealing with AD or related Microsoft products in some fashion. In the enterprise, I almost always deploy to windows products, over the preferred linux+postgres+apache stack, because the business has already invested in resources to manage Windows Server, Microsoft SQL Server, and IIS, in conjunction with AD. Configuration tends to be more platform agnostic, as the applications are Java based, however the number of gotchas that seem to crop up around the Microsoft products make it a big enough pain. It's unfortunate that the link to AD so often blossoms out to the entire infrastructure stack, as the products are in many ways inferior to their open source relatives, but the momentum, support and resources are already there and it doesn't look like changing anytime soon.
