Regular Web Application (SAML2.0)

info

The source code of this project can be found here.

To implement SAML2.0 in a regular web application, you'll need to follow the following steps.

1. Configure an application

Utilize the administration UI to configure a new SAML2.0 SP (Service Provider) client :

1. Open the IdentityServer website at https://localhost:5002.
2. On the Clients screen, click on the Add client button.
3. Select SAML SP and click on next.
4. Fill-in the form like this and click on the Save button to confirm the creation.

Parameter	Value
Identifier	samlSp
Name	samlSp
Metadata URL	http://localhost:5125/Metadata

If the checkbox Use Artifact is checked, then the Artifact binding will be used; if it is not checked, the Post Binding is used by default.

The Public and Private keys are displayed, keep those values into a file, they will be used later during the configuration of the website.

The Public and Private keys are displayed; please save these values in a file as they will be used later during the website configuration.

2. Create ASP.NET CORE Application

Finally, create and configure an ASP.NET CORE Application.

1. Open a command prompt and execute the following commands to create the directory structure for the solution.

mkdir SamlRpWebsite
cd SamlRpWebsite
mkdir src
dotnet new sln -n SamlRpWebsite

2. Create a web project named Website and install the SimpleIdServer.IdServer.Saml.Sp NuGet package.

cd src
dotnet new mvc -n Website
cd Website
dotnet add package SimpleIdServer.IdServer.Saml.Sp

3. Add the Website project into your Visual Studio solution.

cd ..\..
dotnet sln add ./src/Website/Website.csproj

4. Edit the Program.cs file and configure the SAML2.0 authentication.

builder.Services.AddAuthentication(options =>
{
    options.DefaultScheme = "Cookies";
    options.DefaultChallengeScheme = "samlSp";
})
    .AddCookie("Cookies")
    .AddSamlSp("samlSp", options =>
    {
        options.SPId = "samlSp";
        options.IdpMetadataUrl = "https://localhost:5001/master/saml/metadata";
        var currentPath = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
        options.SigningCertificate = X509Certificate2.CreateFromPemFile(Path.Combine(currentPath, "sidClient.crt"), Path.Combine(currentPath, "sidClient.key"));
    });

5. Add a ClaimsController controller with one protected operation.

public class ClaimsController : Controller
{
    [Authorize]
    public IActionResult Index()
    {
        return View();
    }
}

6. Create a view Views\Claims\Index.cshtml with the following content. This view will display all the claims of the authenticated user.

<ul>
    @foreach (var claim in User.Claims)
    {
        <li>@claim.Type : @claim.Value</li>
    }
</ul>

7. "Copy the Private Key obtained from the first step into the sidClient.key file, and the Public Key into the sidClient.crt file.

8. In a command prompt, navigate to the src\Website directory and launch the application.

dotnet run --urls=http://localhost:5125

Finally, browse the following URL: http://localhost:5125/claims. The User-Agent will be automatically redirected to the OpenID server. Submit the following credentials and confirm the consent. You will be redirected to the screen where your claims will be displayed
