Carl and Richard talk to Dominick Baier and Brock Allen about the new version of Thinktecture IdentityServer. As Dominick explains, as soon as you have more than one web application that needs authentication, you want to go to a centralized authentication and authorization scheme, and that's where IdentityServer comes into play. Working with oAuth2 and OpenID Connect, you can create identities for your users from Active Directory, other IMAP stores or just a plain old SQL Server. Take your authentication strategy to the next level!
