I am exploring the options of establishing a wiki site for my company's division of developers, numbering over a hundred. We are a pure Microsoft (Certified Partner) shop, so it is natural to base an implementation on ASP.NET and IIS for familiarity's sake as well as extended learning opportunities.
It looks like Screwturn wiki does not offer a user provider that can hook up to Active Directory. Is there a wiki engine that natively supports AD? Managing two user bases would not be the most efficient of activities when we wish to control access.
