Trouble getting ClaimsPrincipal populated when using EasyAuth to authenticate against AAD on Azure App Service in a Asp.Net Core web app

Question

We have a web app built on Asp.Net core. It doesn\'t contain any authentication middleware configured in it.

We are hosting on Azure App Service and using the Authen

Answer 1

I wrote a small basic middleware to do this. It will create an identity based off of the .auth/me endpoint. The identity is created in the authentication pipeline so that [authorize] attributes and policies work with the identity.

You can find it here:

https://github.com/lpunderscore/azureappservice-authentication-middleware

or on nuget:

https://www.nuget.org/packages/AzureAppserviceAuthenticationMiddleware/

Once added, just add this line to your startup:

app.UseAzureAppServiceAuthentication();
