Certified OpenID Connect implementation.
IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.
Watch this for the big picture: Introduction to OpenID Connect, OAuth2 and IdentityServer - and An Introduction to IdentityServer for a more code-centric talk.
Go to the documentation site.
OpenID Connect specification / OAuth2 specification
IdentityServer is designed as an OWIN/Katana component. By referencing the library or nuget you get a UseIdentityServer extension method for IAppBuilder that allows setting up IdentityServer in your OWIN host:
public void Configuration(IAppBuilder app)
{
var options = new IdentityServerOptions
{
SigningCertificate = Certificate.Get(),
Factory = Factory.Create()
};
app.UseIdentityServer(options);
}Note: If you're hosting in IIS, make sure you enable RAMMFAR in your web.config file.
For more information, e.g.
- support for MembershipReboot and ASP.NET Identity based user stores
