The best Linux Open-source wiki with native support for Windows (NTLM) authentication

I need to set up a wiki for our engineering group; we are part of an Enterprise-wide Windows Active Directory domain. Most of the corporate IT applications use NTLM to authenticate (automatically via Internet Exploder); while I'm not part of corporate IT, I recognize that Single Sign-On (SSO) is important for user acceptance. I am hoping to find a free and open-source wiki that is well-tested and can be hosted on linuxSee End Note 1, while allowing corporate windows laptops to automatically authenticate without a password prompt. I have seen some hacks to make [moin](http://moinmo.in/) authenticate with NTLMSee End Note 2, but I don't know how well this would actually work in practice; so any deployment experiences with moin + NTLM would be valuable. I have also seen [FOS Wiki](http://foswiki.org/) , but [FOS Wiki doesn't seem to have support for automatic login](http://foswiki.org/Support/Question690) . Question: --- In short, I am looking for the best free, open-source, linux wiki implementation with native, automatic NTLM authentication supportSee End Note 3; I give bonus points if it can use [Markdown](http://daringfireball.net/projects/markdown/) or [reStructured Text](http://docutils.sourceforge.net/rst.html) . End Notes: 1. If I felt like running this under Windows, I could use [Screwturn wiki](http://www.screwturn.eu/) ; however, the thought of hosting web services on windows makes me feel all dirty inside. 2. See [this post on wikimatrix](http://www.wikimatrix.org/forum/t51-ntlm-support-windows-authentication) 3. If such a thing even exists
