IdentityServer: Preview of the OpenID Connect Basic Client Profile

The mid term plan is that OpenID Connect will replace the plain OAuth2 endpoints in IdentityServer. As a first step, I just checked in a preview of the OIDC basic client profile support (see this doc).

The preview consists of two parts:

  • OIDC authorize/token/userinfo endpoints for IdSrv
  • ASP.NET client module

To enable the above endpoints, simply uncomment the OIDC routes in ProtocolConfig.cs.

To register an OIDC client, create an OAuth2 code flow client for now:

And adjust the settings in the sample client project web.config accordingly:

<oidcClient clientId=oidccode

            clientSecret=secret

            scope=profile

            issuerName=http://identityserver.v2.thinktecture.com/samples

            signingCertificate=CN=STS>

 

  <endpoints authorize=https://idsrv.local/issue/oidc/authorize

             token=https://idsrv.local/issue/oidc/token

             userInfo=https://idsrv.local/issue/oidc/userinfo />

</oidcClient>

 

The OIDC client module will then automatically redirect to the OpenID provider and coordinate the front/back channel work.

Have fun!

    signing certificate error throwing at below code in OIDC sample(CodeFlowClient). I used the certificate name that was used to configure Identity Server. Should I do anything else?

    var signingcert = X509.LocalMachine.TrustedPeople.SubjectDistinguishedName.Find(config.SigningCertificate, false).First();

    Error:

    I am also getting the same error. Can someone describe the configuration error that I have and how to correct it?
