We're happy to report that our work to support OpenID for Community Server 2008 is done and we can now officially state that Community Server 2008 will support OpenID for authentication!

Jason Alexander, our CTO, started the dotnetopenid project as an open source implementation for Microsoft's .NET platform. The team working on the .NET OpenID implementation has grown along the way and while we've (Telligent) continued to remain active the other members of the open source have also helped us get OpenID working with Community Server.

Community Server has always had support for Single Sign-On. We've found this to be a critical feature for all of our customers since many people have different authentication systems they wish to use or pre-existing systems populated with users. Adding OpenID for Community Server provides yet another way customers can authenticate into Community Server.
