I'm using Asp.net core 2.1 with the full framework. I'm also using Okta.AspnetCore Nuget package 1.1.0. I have setup Okta and it works great in my debugger.

However when I move to IIS 7.5 it gives me an error. I'm guessing that has something to do with kestrel and IIS together but I'm not 100% sure how to fix it.

Error:

2019-02-28 15:14:37,260 [10] ERROR Microsoft.AspNetCore.Server.Kestrel [(null)] - Connection id "0HLKTN5E8L8QB", Request id "0HLKTN5E8L8QB:00000001": An unhandled exception was thrown by the application.

System.InvalidOperationException: No authenticationScheme was specified, and there was no DefaultChallengeScheme found.

This is my setup for Okta in my startup.cs

        services.AddAuthentication(options =>

        {

          options.DefaultAuthenticateScheme = OktaDefaults.ApiAuthenticationScheme;

          options.DefaultChallengeScheme = OktaDefaults.ApiAuthenticationScheme;

          options.DefaultSignInScheme = OktaDefaults.ApiAuthenticationScheme;

        })

        .AddOktaWebApi(new OktaWebApiOptions()

        {

          ClientId = "xxxxxx" // from config file

          OktaDomain = "xxxx.okta.com" // from config file

        });

I'm curious how to setup IIS and kestrel together with Okta.
