How to Setup Azure Active Directory and Integrate ABP Angular Application

This guide demonstrates how to register an application to Azure Active Directory and integrate AzureAD to an ABP Angular application that enables users to sign in using OAuth 2.0 with credentials from Azure Active Directory.

Authentication Flow

ABP Angular application uses Authentication Code with PKCE (specs here) which is the most suitable flow for SPA applications by the time this article is written since implicit flow is deprecated.

The most common question is;

Where to put OpenId connection code in the Angular project?

The answer is, you don't. ABP Angular application is integrated with the backend (HttpApi.Host project) where it loads the configurations, permissions etc. For none-tiered angular applications, HttpApi.Host project also has IdentityServer4 embedded; also serving as Authorization Server. Angular application authentication flow is shown below.


What if I want Azure AD as my authorization server and not IdentityServer?

This means your application will be using AzureAD user store for authentication. By registering both Angular app and HttpApi to AzureAD, authentication might work but authorization won't. Users need to be registered to ABP identity system for auditing, permissions etc. So the flow should be 3rd party registration.

Setting up OpenId Connection

Lets start with adding OpenId connection. Open the HttpApiHostModule.cs and update the ConfigureAuthentication method as below:

    ... //Omitted other third party configurations
    .AddOpenIdConnect("AzureOpenId", "Azure AD OpenId", options =>
        options.Authority = "" + configuration["AzureAd:TenantId"] + "/v2.0/";
        options.ClientId = configuration["AzureAd:ClientId"];
        options.ResponseType = OpenIdConnectResponseType.CodeIdToken;
        options.CallbackPath = configuration["AzureAd:CallbackPath"];
        options.ClientSecret = configuration["AzureAd:ClientSecret"];
        options.RequireHttpsMetadata = false;
        options.SaveTokens = true;
        options.GetClaimsFromUserInfoEndpoint = true;
        options.ClaimActions.MapJsonKey(ClaimTypes.NameIdentifier, "sub");

If you are using tiered (separate identity server) application, open IdentityServerModule.cs and add the OpenIdConnection manually to ConfigureServices method as following:

public override void ConfigureServices(ServiceConfigurationContext context)
    var hostingEnvironment = context.Services.GetHostingEnvironment();
    var configuration = context.Services.GetConfiguration();
        .AddOpenIdConnect("AzureOpenId", "Azure AD OpenId", options =>
            ... // Same configuration above

Now we can add AzureAD settings. Open the appsettings.json located in HttpApi.Host project (or IdentityServer project if you are using tiered application). Add the following;

"AzureAd": {
  "Instance": "",
  "TenantId": "<azureAd-tenant-id>",
  "ClientId": "<azureAd-client-id>",
  "Domain": "",
  "CallbackPath": "/signin-azuread-oidc",
  "ClientSecret": "<azureAd-client-secret>"

Keep on mind that App.SelfUrl + AzureAd.CallbackPath will be used in AzureAD app registration. We'll update the AzureAd settings after registering the application in Azure Portal.

Setting up Azure Active Directory

Navigate to Manage Azure Active Directory in azure portal. Go to App registrations on left side menu and hit New registration.


Enter a name for your application and App.SelfUrl + AzureAd.CallbackPath as redirect uri then register.


Now navigate to Authentication on the left menu and enable ID tokens.


We also need to set a client secret. Navigate to Certificates & secrets menu on the left and create a new client secret.


Copy the secret and update your appsettings.json AzureAd.ClientSecret field.


Also update your AzureAd.TenantId and AzureAd.ClientId fields with the information located under Overview menu. And that's all.

Next time you hit login, you should be seeing login screen enabled Azure AD like below.



  • I am getting errors when trying to login to AzureAD.

  • But I don't want my users to see default login screen. I want my users to login only from AzureAD.

    • You can mimic this behavior by customizing the login page and instantly trigger Azure AD provider click. For more info, you can check this article.

May 2021 Update

  • AddOpenIdConnect: Removed JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear(); and added sub claim mapping in ClaimActions rather than global mapping.
  • Updated OpenIdConnect configurations.

I did the above code settings and the settings in the azure portal as you said. Clicking the Azure Ad Open Id button redirects me to the microsoft login page, after entering the username, the password screen should appear, but I get the page not found error. But if I have logged into the microsoft site before, it will let me in directly. I do not get an error.

Hello, if you are getting page not found error; its high probably related with your Azure application registry. Try double checking you set your TenantId and ClientId on appsettings.json correctly.

Hi, I managed to set up your code on a third party architecture (separate IdentityServer). When I log in from IdentityServer it works fine. but when I log in from Blazor I have the following error: Page not found .... Any Idea ?

Hi, has anyone been able to solve the issue that mentioned here?

I am experiencing the same problem with Blazor template (separated IdentityServer). Any help would be greatly appreciated.

Galip Tolga ERDEM 153 weeks ago

It is related with your account that is trying to login. Probably you are trying to login with your personal account while AzureAD is expecting a user existing in AzureAD users. You can check and for more details.

Excellent article - works nicely in Blazor!

Is there any way to override the Login Page similar to that demonstrated in the MVC project?

Halil İbrahim Kalkan 184 weeks ago

The Blazor UI uses the MVC UI for the login page. So, you can use the same system to override the pages. Do it in the server side (Http API Host) application.

Hi, In my HttpApi.Host, i have : .AddJwtBearer(options => { ......... }; }) shoud i keep it and add the OpenId config or drop it and add your code as it? when i do so i got error. " can't find AddIdentityServerAuthentication in AuthenticationBuilder" i'm using ABP 3.2.1 UI Angular not tiered. Please help. Regards

+1 having same issue - new sample for blazor would be great. For me I kept it as the app still needs to get Authorization data from IS4. Have a look at the issue (link below) it has some of my code in the comments. Not 100% working as the username is lost for auditing purposes but it does work well and users can choose either normal login or using AD Azure.

Be awesome to see a sample using template as follows: abp new Acme.BookStore --ui blazor --separate-identity-server because a few of us trying to adapt this article are having a few difficulties ( Cheers

i'm getting this error :

[11:20:09 DBG] CORS request made for path: /api/abp/application-configuration from origin: http://localhost:4200 but was ignored because path was not for an allowed IdentityServer CORS endpoint [11:20:09 INF] No CORS policy found for the specified request.

any idea ?

How do I map custom user property (like Group Name ) from Azure AD to ABP Users Table? and then use them in the app

jakeuj 138 weeks ago

You can login only from AzureAD by disable local login. "Settings": {"Abp.Account.EnableLocalLogin": true}, and Update [IdentityServerClients] set [EnableLocalLogin] = false. I think this doc should be added to "". (

Hi, great article! Would Azure AD B2C integration be similar or does it need additional steps?

Hi, it is working perfectly , but what if i want to assign a default role to this new registered user?

Galip Tolga ERDEM 108 weeks ago


You need to override Account/Login.cshtm and override OnGetExternalLoginCallbackAsync method. After a new user is created, you can assign a default new role.

Great article - but it would be awesome if there were a sample project in github for this (like the one for an MVC ABP project). Apologies if this is already available but I couldn't find a link.
