Blazor Webassembly asp.net hosted with Microsoft Azure AD authentication

Question

I found a lot number of examples how o do this. https://docs.microsoft.com/en-us/aspnet/core/blazor/security/webassembly/hosted-with-azure-active-directory?view=aspnetcore-6.0 And it works fine when I run it locally in debug.

Everything is fine, until I want to publish the application up to an Azure APP Service.

1. I create an App Service and connect the server registration to it
2. I add on the client registration the URL of the APP Service https://xxxxx.azurewebsites.net/authentication/login-callback
3. In Visual Studio 2022 I publish the server application up to the App Service

To my surprise, the application does not work from the published site...

I get the response:

Sign in
Sorry, but we're having trouble signing you in.

AADSTS700054: response_type 'id_token' is not enabled for the application.

I can not find an example that go all the way to a published APP service...

So what is wrong in my thinking here?

Answer 1

You need to register the app in Azure AD.

Your error message is: "'id_token' is not enabled for the application"

To fix this under Advanced Settings, Implicit grant check the box "ID tokens".
