Blazor SAML SSO with Okta as IDP

Blazor SAML Single Sign-On (SSO) application gives the ability to enable SAML Single Sign-On for your Blazor applications. Using Single Sign-On you can use only one password to access your Blazor application and services. Our application is compatible with all the SAML compliant Identity providers. Here we will go through a step-by-step guide to configure Single Sign-On (SSO) between Blazor and Okta considering Okta as IdP. To know more about the features we provide for Blazor SSO, click here.

Steps to configure Blazor Single Sign-On (SSO) using Okta as IDP

Step 1: Pre-requisites: Download And Installation

• Install the Blazor SAML SSO Middleware in your application package using the nuget package

      

          
          
    
    using miniorange.saml
    public class Startup
    {
      public void ConfigureServices(IServiceCollection services)
      {
   
       services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie();
       services.AddControllersWithViews();
      }
      public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
      {
        app.UseHttpsRedirection();
        app.UseRouting();
        app.UseAuthorization();
        app.MapRazorPages();
    
        app.UseCookiePolicy();
        app.UseAuthentication();
        app.UseStaticFiles();
        app.UseminiOrangeSAMLSSOMiddleware();
        app.Run();
      }
    }
    
    
    

      

          
    
    using Microsoft.AspNetCore.Authentication.Cookies;
    using miniOrange.saml;
    
    var builder = WebApplication.CreateBuilder(args);
    
    builder.Services.AddRazorPages();
    // Add authentication services
    builder.Services.AddControllersWithViews();
    builder.Services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie();
    
    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();
    
    
    

• After integration, open your browser and browse the connector dashboard with the URL below:
  https://<blazor-application-base-url>/?ssoaction=config
• If the registration page or login page pops up, you have successfully added the miniOrange ASP.NET SAML SSO connector to your application.

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

3. Configure Blazor SAML application as Service Provider

There are two ways detailed below with which you can configure your SAML identity provider metadata in the application.

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 application using the Upload IDP Metadata option.
• 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 application 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.
• In free plugin you can configure only NameID
• Note: All the mapped attributes will be stored in the claims 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 Blazor 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:

          

      

  string name="";
  string claimtype="";
  string claimvalue="";

   if(User.Identity.IsAuthenticated)
   {
     foreach( var claim  in User.Claims) 
     {
       claimtype = claim.Type;
       claimvalue = claim.Value;
     }
     retrive custom attributes(for eg. Retrieve Mapped 'mobileNumber' attribute of your IDP)
     var identity = (ClaimsIdentity)User.Identity;
     IEnumerable claims = identity.Claims;
     string mobileNumber = identity.FindFirst("mobileNumber")?.Value;
   }

• Note: All the mapped attributes will be stored in the claims to be accessed in your application.
