Pre-requisites : Download And Installation

• Version .NET 5 & Above
• Version .NET Core 2.1 & .NET Core 3.1

NuGet Packege

.NET CLI

PM> NuGet\Install-Package miniOrange.SAML.SSO

> dotnet add package miniOrange.SAML.SSO

Note: To integrate the miniOrange ASP.NET SAML SSO middleware in your application, you will be required to add the below namespaces, services and middleware in your project, below is a sample implementation for reference.

  using miniOrange.saml;
  using System.Reflection;
  var builder=WebApplication.CreateBuilder(args);
  // Add services to the container.
  builder.Services.AddRazorPages();
  builder.Services.AddminiOrangeServices(Assembly.GetExecutingAssembly());
  var app = builder.Build();
  if(!app.Environment.IsDevelopment())
  {
    app.UseExceptionHandler("/Error");
    app.UseHsts();
  }
  app.UseHttpsRedirection();
  app.UseRouting();
  app.UseAuthorization();
  app.MapRazorPages();
  app.UseCookiePolicy();
  app.UseAuthentication();
  app.UseStaticFiles();
  app.UseminiOrangeSAMLSSOMiddleware();
  app.Run();

1. Add middleware on ASP.NET Core application

• After integration, open your browser and browse the connector dashboard with the URL below:
  https://<asp.net-middleware-base-url>/?ssoaction=config

• If the registration page or login page pops up, you have successfully added the miniOrange ASP.NET middleware authentication SAML SSO connector to your application.

• Register or log in with your account by clicking the Register button to configure the middleware.

There are two ways detailed below with which you can get the SAML SP metadata to configure onto your Identity Provider end.

A] Using SAML metadata URL or metadata file

• In the Plugin Settings menu, look for Service Provider Settings. Under that, you can find the metadata URL as well as the option to download the SAML metadata.

• Copy metadata URL or download the metadata file to configure the same on your identity provider end.

• You may refer to the screenshot below:

B] Uploading metadata manually

• From the Service Provider Settings section, you can manually copy the service provider metadata like SP Entity ID, ACS URL, Single Logout URL and share it with your identity provider for configuration.

• You may refer to the screenshot below:

3. Configure ASP.NET Core SAML Middleware as Service Provider

There are two ways detailed below with which you can configure your SAML Identity Provider metadata in the middleware.

A] Upload metadata using the Upload IDP Metadata button:

• If your identity provider has provided you with the metadata URL or metadata file (.xml format only), then you can simply configure the identity provider metadata in the middleware using the Upload IDP Metadata option.

• Copy metadata URL or download the metadata file to configure the same on your identity provider end.

• You may refer to the screenshot below:

• You can choose any one of the options according to the metadata format you have available.

B] Configure the identity provider metadata manually:

• After configuring your Identity Provider, it will provide you with IDP Entity ID, IDP Single Sign On URL and SAML X509 Certificate fields respectively.

• Click Save to save your IDP details.

4. Testing SAML SSO

• Click on the Test Configuration button to test whether the SAML Configuration you’ve done is correct.

• The screenshot below shows a successful result. Click on SSO Integration to further continue with the SSO Integration.

• If you are experiencing any error on the middleware end you’ll be shown with the window similar to below.

• To troubleshoot the error you can follow the below steps:

• Under Troubleshoot tab, enable the toggle to receive the plugin logs.

• Once enabled, you will be able to retrieve plugin logs by navigating to Plugin Settings tab and clicking on Test Configuration.

• Download the log file from the Troubleshoot tab to see what went wrong.

• You can share the log file with us at aspnetsupport@xecurify.com and our team will reach out to you to resolve your issue.

5. Attribute Mapping

• After testing the configuration, Map your application attributes with the Identity Provider (IdP) attributes.

• Note: All the mapped attributes will be stored in the session so that you can access them in your application.

6. Integration Code

• This steps allow you to retrieve the SSO user information in your application in the form of user claims.

• You can also look the setup tour to understand how the SSO integration would work in your asp.net middleware application.

• Just copy-paste that code snippet wherever you want to access the user attributes.

• Note: This trial middleware only supports user information in claims, retrieving user information in session and headers is available in the premium plugin

• You can also copy the integration code from below:

7. Login Settings

• Hover on Select Actions and click on Copy SSO Link.

• Use the following URL as a link in the application from where you want to perform SSO:
https://asp.net-middleware-base-url/?ssoaction=login

• For example, you can use it as:
<a href=”https://asp.net-middleware-base-url/?ssoaction=logout”>Log out</a>

8. Logout Settings

• Use the following URL as a link to your application from where you want to perform SLO:
https://asp.net-middleware-base-url/?ssoaction=logout

• For example, you can use it as:
<a href=”https://asp.net-middleware-base-url/?ssoaction=logout”>Log out</a>
