Hi All,

I needed to add openid support via identity server 4 (set up to use ASP.NET Identity) so users can log into the back office of umbraco.

I followed this tut: https://yuriburger.net/2017/04/26/login-to-umbraco-backoffice-using-identityserver4/

I have everything the button showing on the login screen:

Now when I click the button it goes off to Identity Server and I log in then it redirects me my mysite/umbraco , but it hasn't logged me in.

Here's the main code I'm using the the custom Owin Startup:

 var identityOptions = new OpenIdConnectAuthenticationOptions
        {
            ClientId = "umbracoBackoffice",
            SignInAsAuthenticationType = Constants.Security.BackOfficeExternalAuthenticationType,
            Authority = "https:localhost:5000",
            RedirectUri = "https://mysite/umbraco",
            ResponseType = "code id_token token",
            Scope = "openid profile email application.profile",
            PostLogoutRedirectUri = "https:localhost:5000"
        };

        // Configure BackOffice Account Link button and style
        identityOptions.ForUmbracoBackOffice("btn-microsoft", "fa-windows");
        identityOptions.Caption = "OpenId Connect";

        // Fix Authentication Type
        identityOptions.AuthenticationType = "https:localhost:5000";

        // Configure AutoLinking
        string[] userTypes = new string[] { "administrator", "editor" };
        identityOptions.SetExternalSignInAutoLinkOptions(
            new ExternalSignInAutoLinkOptions(autoLinkExternalAccount: true, defaultUserGroups: userTypes));

        identityOptions.Notifications = new OpenIdConnectAuthenticationNotifications
        {
            SecurityTokenValidated = ClaimsTransformer.GenerateUserIdentityAsync
        };

        app.UseOpenIdConnectAuthentication(identityOptions);

Any ideas?
