I want to set up a wiki for my team. I need it to run on Windows/IIS and if it needs a database, against SQL Server.
User-authentication must use/integrate with Active Directory, ideally natively rather than using LDAP.
Ideally, authorization would use Active Directory groups rather than something internal.
The ideal wiki would run on Server 2008 R2 x64, IIS 7.5 and SQL Server 2008 but these aren't requirements, just nice-to-haves.
Is there anything that fits these requirements and would you recommend it.
