What is the Wiki engine on .net with NTLM?

Question

ASP.NET

Good afternoon, I'm looking for a wiki site engine for a corporate environment. The main condition for being on .net was the ability to authorize via NTLM and I would very much like to be able to break links into categories (meaning when writing an article on the wiki, entering {{ to create a hyperlink loaded a list of all articles that can be referenced, and they fought in predetermined categories).
So far, more or less suitable, what I have installed and tested, is RoadKill , but there is no third paragraph with a breakdown of article links.
Thanks in advance for advice.
