I have IIS 7 (Windows Server 2008 R2) and TFIM front-ending the users so that by the time the request hits IIS there's a SAML token presented via WS-Fed.
What I am trying to understand is, what's needed to be installed or configured on the IIS side to consume this token?
Do you have to change the Authentication module in IIS to something else? Anything else?
Do I need to install anything in particular?
In the Microsoft world, applications that use an STS (like ADFS or TFIM) that uses the WS-Federation protocol to authenticate use WIF to process the claims that are enclosed in the SAML token.
There's nothing IIS specific.

I am trying to create a login mvc application in .NET through which any identity provider that supports OpenIdConnect for authentication and Oauth2.0 for authorization should be able to communicate. The objective is all my microservices will then call the login service ( which will act as a proxy) to perform single login and single logout and authorization via different identity providers such as Ping Identity or Okta or perhaps Azure AD. I am using the package Microsoft.AspNetCore.Authentication.OpenIdConnect to achieve this.
I don't have much experience setting up ADFS authentication in the .NET stack so forgive my ignorance if I am missing the obvious. But if some one can point me in the direction on how to configure ADFS and write a .NET Core application to request Oauth2.0 supported tokens from it, would help a lot. Please know that I am trying to connect with ADFS 2012 R2 , which supports Oauth2.0 Authorization code flow.
ADFS 2012 R2 does not support OpenID Connect and has no concept of an ID token.
You need to use ADFS 2016 or above.
We are using Identity Server 3 in our tool that has the following structure. One (AngularJs) Spa with 10 Web APIs . We use the WindowsAuthWebHost mini project to do the windows handshake to get the windows(domain) identity of the user, based on which we build a complex(with custom claims) token that it's used by the client Web APIs. All the 10 Web APIs have anonymous authentication set in the IIS. And it works smoothly.
Now, we are trying to expose this tool outside the company network and a perquisite is to have windows authentication on all the Web APIs in the IIS. If we set this time of authentication, now all the calls are unauthorized.
Do you know if there is a way to keep the same flow, but also validated the windows authentication?
Windows authentication will not work outside of the network. The user needs to have a valid user account in your domain (username/password), or even a local account on your IIS server.
Note that NTLM doesn't work through some proxy servers, so this is one reason that Windows AuthN isn't used so much on the public internet.
To achieve your requirement you could use the form authentication with active directory.you may need to enable both form and anonymous authentication. then create deny authorization rule for anonymous users and allow rule for all users.
How To: Use Forms Authentication with Active Directory in ASP.NET 2.0
I know about ASP.NET Authentication mode (Form, Windows and Passport) and we have used mostly Form based authentication for our web applications. I want to know how IIS takes part in authentication, does it pre-authenticates the request before passing it to the ASP.NET. How can I configure IIS authentication ?
Very broad topic, but essentially, IIS does not authenticate if anonymous authentication is enabled. This relies on the application to do any required authentication (such as Forms, as you mentioned)
If anonymous is turned off, IIS can authenticate using the following methods:
Basic: credentials passed as http header with each request
Digest: sort of a more-secure basic; the password is hashed
Windows: uses client's windows credentials to authenticate
Certificate: requires a specific x509 certificate to be sent by the client

I am creating a .NET 4.5 WCF web service for deployment on Windows Server 2008 running IIS 7.0. I want my web service to identify the users who access the service by authenticating a Kerberos token string that is passed through the web service. I can't use Integrated Windows Authentication (some of my clients are using Linux machines) so, I must pass the token string. Does anyone know how I can do the following:
Generate a Kerberos token string in C# .NET 4.5 based a users current identity.
Validate a Kerberos token string in C# .NET 4.5 and get the associate username.
Thanks!
You could maybe expose the service with two bindings, one for Windows-users with Windows-authentication and one for others using user name authentication. Is it an intranet or internet scanario? How are the Linux users identified?
My production environment involves a pair of IIS 6 web servers, one running legacy .NET 1.1 applications and the other running .NET 2.0 applications. We cannot install .NET 2.0 alongside 1.1 on the same machine because it is a tightly-regulated 'Validated System' and would present a bureaucratic nightmare to revalidate.
Websites on both servers use Basic Authentication against Active Directory user accounts.
Is it possible for a web application on the 1.1 server to securely redirect a user to a page served on the 2.0 server, without requiring users to re-authenticate?
No, because you're not using cookies for authentication in that scenario, so ScaleOvenStove's link won't help.
Basic authentication sends the login information in the HTTP headers with every request, but it's the browser that does this, when it sees a new server, new password request.
(Or indeed as suggested change the authentication on both systems to support single signon)
In order to achieve this you could implement a single sign-on solution.
This solution would have one server be your master authentication server. This server would be responsible for authentication and creating a cookie for the user. When you redirect to the other server (on the same domain) check to see if the authentication cookie exists that was created by the authentication server, and if it exists, and has valid data, auto login the user. Make sure that you set the domain on the forms authentication ticket and cookie, and then both servers which exist on the same domain will be able to access this cookie.
I would google single sign on asp.net. There's a number of ways to achieve it, but it's definitely achievable.
