I have issue with configuration of OpenID Connect with Sitecore Federated Authentication. On the final step of login process in the call to /identity/externallogincallback the cookies are missing. I do not understand it is caused by my configuration or I missing something. The description is shown below.

Issue: Federated Authentication with OpenID Connect is not working. After typing credentials error showed below occurs:

ERROR Unable to get and an external login info via Microsoft.Owin.Security.AuthenticationManagerExtensions.GetExternalLoginInfoAsync. Most probably the identity does not have a 'http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier' claim.

The final /identity/externallogincallback request does not contain any cookies required for authentication. Then the authentication returns failure.

Description It looks the login process is working correct to the final step. The method OnSecurityTokenValidated inside OpenIDIdentityProviderProcessor is invoked and run without errors. The claims are loaded correctly and the debuger says that user is authenticated.

enter image description here

From the debugging I see that the login process is correct, then the /identity/signin-openID POST is called (it is set as redirect URI). It is called without any cookies. Then the /identity/externalcallogincallback is set and there is also any cookies into that request. It causes that inside the Sitecore.Owin.Authentication.Pipelines.Initialize.HandleLoginLink.HandleExternalLoginCallbackUrl the code

await context.Authentication.GetExternalLoginInfoWithWhitespacesAsync().ConfigureAwait(false);

is returning null and then the error Error: Unsuccessful login with external provider. is shown on page.

Nuget Packages:

  • Sitecore.Owin 9.1.1
  • Sitecore.Owin.Authentication 9.1.0
  • Microsoft.Owin.Security.OpenIdConnect 4.0.0

The redirectURI is defined as:

  <!-- your Sitecore instance Url-->
  <setting name="OpenID.RedirectUri" role:require="Standalone or ContentManagement">
    <patch:attribute name="value">https://site.sc/signin-openID</patch:attribute>
  </setting>

The federated authentication config is shown below. The Identity server is disabled.

  • There are too many things in your question. Can you please ask what is the issue and error msg what you are facing ? – Abhay Dhar Mar 12 at 2:17
  • Hi @AbhayDhar. Thank you for your message. I've investigated the issue more and reword my post. I would appreciate if you look on it again :) Best regards – klucyszy Mar 12 at 20:25
  • I had implemented via Azure Adb2c - pl chk this for config and code example - sitecore.stackexchange.com/questions/22947/… – Abhay Dhar Mar 13 at 14:25

after talk with Sitecore supports, it appears that all configuration looks good. The one thing that differ from their and my implementations approach of OpenId noticiations. After using Support's approach the OpenId starts working.

Notifications = new OpenIdConnectAuthenticationNotifications
{
    AuthenticationFailed = notification =>
    {
        ...
        return Task.CompletedTask;
    },
    SecurityTokenValidated = notification =>
    {
        ...
        return Task.CompletedTask;
    }
}
