Internal/External knowledgebase with AD integration?

[Resolver]

I've been searching Joomla, and doing some googling, but can't quite find what I'm looking for.

 

I'd like to find an open source knowledge base that would allow us to set content/categories to be viewed only by internal users (by using AD authentication would be ideal), or viewable to both internal users and outside customers via a webportal.

 

Thanks for any suggestions.

I ended up using phpMyFAQ homepage - open source FAQ system for PHP and MySQL, PostgreSQL and other databases | welcome It's an open source linux project that provides a lot of functionality. The interface could be prettier, and the way it provides AD integration could be more secure (a user/pass is sent in plain text across the network to authenticate the provided user, instead of using the users credentails and doing it in an encrypted way. the user/pass is sends is stored in plaintext in the phpmyfaq folder).

 

That aside, it allows for group creation and provides very granular controls on who can see what. I posted a basic howto on their forum for linux newbies to integrate the software into a windows 2003 environment.
