Easy Auth is a great way to authenticate your users. However, when used in the context of Azure Container Apps, .NET applications do not, by default, recognise that Easy Auth is in place. You might be authenticated but .NET will still act as if you aren't. builder.Services.AddAuthentication() and app.UseAuthentication() doesn't change that. This post explains the issue and solves it through the implementation of an AuthenticationHandler.

I've written lately about zero downtime releases with Azure App Service. Zero downtime releases are only successful if your authentication mechanism survives a new deployment. We looked in my last post at how to achieve this with Azure's in-built authentication mechanism; Easy Auth.

I wrote recently about zero downtime deployments on Azure App Service. Many applications require authentication, and ours is no exception. In our case we're using Azure Active Directory facilitated by "Easy Auth" which provides authentication to our App Service.

I wrote recently about how to get Azure App Service Easy Auth to work with roles. This involved borrowing the approach used by MaximeRouiller.Azure.AppService.EasyAuth.

As a consequence of writing that post I came to learn that official support for Azure Easy Auth had landed in October 2020 in v1.2 of Microsoft.Identity.Web. This was great news; I was delighted.

However, it turns out that the same authorization issue that MaximeRouiller.Azure.AppService.EasyAuth suffers from, is visited upon Microsoft.Identity.Web as well. This post shows hoew to resolve it with IClaimsTransformation.

Azure App Service has a feature which is intended to allow Authentication and Authorization to be applied outside of your application code. It's called "Easy Auth". Unfortunately, in the context of App Services it doesn't work with .NET Core and .NET. Perhaps it would be better to say: of the various .NETs, it supports .NET Framework. To quote the docs:

At this time, ASP.NET Core does not currently support populating the current user with the Authentication/Authorization feature. However, some 3rd party, open source middleware components do exist to help fill this gap.

Thanks to Maxime Rouiller there's a way forward here. However, as I was taking this for a spin today, I discovered another issue.
