Auth0 Headless Kerberos authentication for the AD Connector

Sample project showing how to do headless Kerberos authentication with Auth0 (for Console Applications, Windows Services, ...)

Key features

Use "Integrated Windows Authentication" (Kerberos) from your Console applications, Windows Services, ... with Auth0. This allows you to have Kerberos support for headless application that run in the context of a Windows User (on a Domain Joined machine).


First you'll need to configure your application in Auth0. Add the following URL as a Callback URL in Auth0:


Then add the required settings in the App.config/Web.config:

<add key="auth0:Domain" value="" />
<add key="auth0:ClientID" value="yNqQMENaYIONxAaQmrct341tZ9joEjTi" />
<add key="auth0:ConnectionName" value="FabrikamAD" />

And now you can use the AdConnectorClient for headless Kerberos authentication and to get a token for the current user:

var client = new AdConnectorClient(
	"openid email nickname");

var result = client.Authenticate();
foreach (var item in result)
	Console.WriteLine(" > {0}: {1}", item.Key, String.Join(", ", item.Value));

Note: Since you can specify the scope used for authentication, you can ask for additional information or even request a refresh token.


What is Auth0?

Auth0 helps you to:

  • Add authentication with multiple authentication sources, either social like Google, Facebook, Microsoft Account, LinkedIn, GitHub, Twitter, Box, Salesforce, amont others, or enterprise identity systems like Windows Azure AD, Google Apps, Active Directory, ADFS or any SAML Identity Provider.
  • Add authentication through more traditional username/password databases.
  • Add support for linking different user accounts with the same user.
  • Support for generating signed Json Web Tokens to call your APIs and flow the user identity securely.
  • Analytics of how, when and where users are logging in.
  • Pull data from other sources and add it to the user profile, through JavaScript rules.

Create a free Auth0 Account

  1. Go to Auth0 and click Sign Up.
  2. Use Google, GitHub or Microsoft Account to login.
