We are implementing Azure AD Authentication in ASP.NET MVC 5 using Open ID Connect. When the application was running on premise we had windows Authentication, so there is no login page or Login button.
We have put [Authorize] attribute to all the controllers so that the user is authenticated before accessing the page. Below is the code in start up Auth.
    app.UseKentorOwinCookieSaver();
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = "Cookies",
            CookieManager = new Microsoft.Owin.Host.SystemWeb.SystemWebChunkingCookieManager()
        });
        app.UseOpenIdConnectAuthentication(
            new OpenIdConnectAuthenticationOptions
            {
                ClientId = clientId,
                Authority = authority,
                PostLogoutRedirectUri = postLogoutRedirectUri,
                RedirectUri = RedirectUri,
                ResponseType = OpenIdConnectResponseType.Code,
                Notifications = new OpenIdConnectAuthenticationNotifications()
                {
                    AuthenticationFailed = (context) => {
                        context.HandleResponse();
                        return Task.FromResult(0);
                    }
                }
            }); 
But we are facing the Infinite loop once the user is authenticated. And I tried all the solutions on internet, but my issue is not solved.
