Repunjay_TASC created 2 months ago

ABP Framework version: 7.4.2
UI Type: Angular
Database System: EF Core (PostgreSQL)
Tiered (for MVC) or Auth Server Separated (for Angular): yes
Exception message and full stack trace:
Steps to reproduce the issue:
How to integrate SSO Integration Using OAuth2/OpenID Connect ?
If above mentioned integrations possible with my current application, Could you please provide documentation/guides/steps to do the same.

However, I have added very high level analysis code please go thought it and let me know correct or not ?

Step 1: Add NuGet Packages Ensure you have the following packages installed in our Gateway web project :

Step 2: Configure appsettings.json

Add the OpenIdConnect settings to gateway appsettings.json:

{ 
  "Authentication": { 
    "OpenId": { 
      "Authority": "https://{yourOktaDomain}/oauth2/default", 
      "ClientId": "{yourClientId}", 
      "ClientSecret": "{yourClientSecret}", 
      "ResponseType": "code", 
      "SaveTokens": true, 
      "GetClaimsFromUserInfoEndpoint": true, 
      "Scope": "openid profile email" 
    } 
  } 
} 


3. Update the `ConfigureServices` and `Configure` methods to set up authentication:  


//The code you provided configures authorization policies in your application,
specifically setting a default authorization policy that requires users to be authenticated
using either the primary JWT Bearer scheme or the OIDC JWT Bearer scheme.

 private static void ConfigureAuthentication(ServiceConfigurationContext context, IConfiguration configuration)
        {

            context.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
                .AddJwtBearer(JwtBearerDefaults.AuthenticationScheme, options =>
                {
                    options.Authority = configuration["AuthServer:Authority"];
                    options.RequireHttpsMetadata = false;
                    options.Audience = configuration["AuthServer:ApiResource"];
                })
                .AddJwtBearer("OIDC", options =>
                {
                    options.Audience = configuration["AuthServer:ApiResource"];
                    options.RequireHttpsMetadata = false;
                    options.Authority = configuration["AuthServer:Authority"];
                });
            Log.Information($"ApiResource: {configuration["AuthServer:ApiResource"]}");

            // Authorization
            context.Services.AddAuthorization(options =>
            {
                var defaultAuthorizationPolicyBuilder = new AuthorizationPolicyBuilder(
                    JwtBearerDefaults.AuthenticationScheme,
                    "OIDC");
                defaultAuthorizationPolicyBuilder =
                    defaultAuthorizationPolicyBuilder.RequireAuthenticatedUser();
                options.DefaultPolicy = defaultAuthorizationPolicyBuilder.Build();
            });
        }
       


public void ConfigureServices(IServiceCollection services) 
    { 
	need to discuss commented code
        //services.AddAuthentication(options => 
       // { 
          //  options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme; 
          //  options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme; 
        //}) 
       // .AddCookie() 
        .AddOpenIdConnect(OpenIdConnectDefaults.AuthenticationScheme, options => 
        { 
            options.Authority = Configuration["Authentication:OpenId:Authority"]; 
            options.ClientId = Configuration["Authentication:OpenId:ClientId"]; 
            options.ClientSecret = Configuration["Authentication:OpenId:ClientSecret"]; 
            options.ResponseType = Configuration["Authentication:OpenId:ResponseType"]; 
            options.SaveTokens = Configuration["Authentication:OpenId:SaveTokens"]; 
            options.GetClaimsFromUserInfoEndpoint = Configuration["Authentication:OpenId:GetClaimsFromUserInfoEndpoint"]; 
            options.Scope.Add("openid"); 
            options.Scope.Add("profile"); 
            options.Scope.Add("email"); 
        }); 
    }
	
public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
	 app.UseAuthentication(); 
         app.UseAuthorization(); 
}

modules\Identity-core\src\Identity.HttpApi\Controllers\OIDC\OIDCController.cs

Note :-  AuthenticationSchemes we can use Controllers or Method level as well
namespace Identity.Controllers.OIDC
{    
    [Route("api/OIDC")]
    [Authorize(AuthenticationSchemes = "OIDC")]
    public class OIDCController : AbpController, OIDCAppService
    {
    }
	
    [Authorize("OIDC")]
    public Task CreateAsync(CreateAuthorDto input)
    {
    }
	
      all IDP  end points. 
}

Hi,

To integrate SSO Integration, you need to share cookies between subdomains

see https://learn.microsoft.com/en-us/aspnet/core/security/cookie-sharing?view=aspnetcore-8.0

Thanks for response.

Above code i have mention is it correct way to implement for SSO. However, I'll add cookies code between subdomains.

Hi,

you don't need to add OAuth2 to the gateway.

Hi,

you don't need to add OAuth2 to the gateway.

But, Our identity server URL is configured in the API Gateway. Whenever I access any identity server API, I first redirect through the API Gateway, which then internally calls the identity server API.

However, If you have any references or step-by-step guidance on how to integrate OIDC SSO, could you please provide project link or details?

I am still confuse because as per below abp.io support ticket i have follow instruction. https://abp.io/support/questions/5427/HOW-TO-AUTHENTICATE-EXERNAL-SSO-TOKEN-WITH-ADMIN-APIS

You mentioned that the code I provided might not be necessary for handling SSO integration using cookies across subdomains. However, the step-by-step details are not clearly outlined. Could you provide a more detailed explanation or clarification? https://learn.microsoft.com/en-us/aspnet/core/security/cookie-sharing?view=aspnetcore-8.0

My requirement :- The users authenticated through an external SSO are not our application users; the only similarity is the email address. After the user is authenticated via SSO, authorization is managed within our application.

here is talking about configure extra authentication. These are already configured by default in the abp template

Here is abp.io how to configure SSO. You need to configure it for all applications

oh, you need to configure an external OIDC provider in the authserver project
