Thread:Project:Support desk/AD and SSO extensions

Hello guys. I have a question for anyone willing. I'm getting a bit confused with all of the different extensions for both SSO and AD/LDAP integration, so I wanted to get some advice:

MediaWiki: Newest version, running on Windows 2008 R2 on WAMP

What I would like to do is authenticate users with my AD environment. When they access my Wiki, I would like them to be auto-authenticated with their current login credentials. I would also like the ability to restrict certain pages from individuals or groups to keep certain company information close hold to a specific set of users. I've seen about a million different extensions, so could anyone suggest the ones that would best meet these needs? I'd appreciate it!
