@kasitimo thanks for your interest in the project! Please can you upload your source code so I can have a closer look?

If not you need to add a authentication scheme with you CustomScheme key as per the docs http://ocelot.readthedocs.io/en/latest/features/authentication.html

@TomPallister please guide to setting authentication in program.cs

@kasitimo change your program.cs to this and Ocelot will start and delete Startup.cs your code doesnt use it.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Logging;
using Ocelot.Middleware;
using Ocelot.DependencyInjection;

using Microsoft.AspNetCore.Builder;

namespace APIGateway

    public class Program
    {
        public static void Main(string[] args)
        {
            new WebHostBuilder()
               .UseKestrel()
               .UseContentRoot(Directory.GetCurrentDirectory())
               .ConfigureAppConfiguration((hostingContext, config) =>
               {
                   config
                       .SetBasePath(hostingContext.HostingEnvironment.ContentRootPath)
                       .AddJsonFile("appsettings.json", true, true)
                       .AddJsonFile($"appsettings.{hostingContext.HostingEnvironment.EnvironmentName}.json", true, true)
                       .AddJsonFile("ocelot.json")

                   s.AddAuthentication(options =>
                    {
                        options.DefaultScheme = "CustomAuth";
                        //options.DefaultAuthenticateScheme = "CustomScheme";
                        //options.DefaultChallengeScheme = "CustomScheme";
                    })
                    .AddCustomAuth("CustomAuth", o => { });
                    s.AddOcelot();
               })
               .ConfigureLogging((hostingContext, logging) =>
               {
                   //add your logging
               })
               .UseIISIntegration()
               .Configure(app =>
               {
                   app.UseAuthentication();
                   app.UseOcelot().Wait();
               })
               .UseUrls("http://localhost:9000")
               .Build()

    }

It work!!
Thank you for your help

[TomPallister]

@kasitimo no problem :)

[kasitimo]

@TomPallister I have some question ocelot support multiple AuthenticationProviderKey in AuthenticationOptions ?

eg.
"AuthenticationOptions": {
"AuthenticationProviderKey": ["Auth2","Auth2"]
}

[TomPallister]

@kasitimo not at the moment, Im not sure if asp.net core can do this!

[ahmadtec]

.AddCustomAuth("CustomAuth", o => { });

When I apply your code I got an error on that line of code
"IServiceCollection" does not contain a definition for "AddCustomAuth"

@TomPallister i have a doubt the above same code doesn't work with Azure AD JWT provider with "AzureAdJWTBearer" as provider key, it says unsupported authentication provider key and doesn't start the ocelot.
