Before I forget (again), does anyone have any suggestions for Wiki software that runs on Windows and integrates into Windows authentication for access control? Such that you can have pages viewable to some and not others, editable by one group and only readable by another, etc. Preferably .Net/C#, but that's not really critical. DB could be MS SQL Server or MySQL, I'd rather not introduce yet another DB into the environment. The leading recommendation I have right now is for Perspective.
