Why is Hangfire requiring authentication to view dashboard - asp.net-mvc

Question

I am running HangFire within my MVC web app but whenever I try to navigate to http://MyApp/hangfire, it redirects me to my app's login page as though I am not logged in.
I have not explicitly configured any requirements for authorization...e.g. I had the below in the web.config, but then took it out in attempts to get this to work.
<location path="hangfire">
<system.web>
<authorization>
<allow roles="Administrator" />
<deny users="*" />
</authorization>
</system.web>
In theory, this is what I'd want, and when I log into my main web application, I will be logged in with an Administrator role so this rule should work.
But whether I have that configured in the web.config or not, whenever I try to navigate to http://MyApp/hangfire, it redirects me to my apps login page as configured in the web.config:
<authentication mode="Forms">
<forms loginUrl="~/Account/Login" timeout="960" />
</authentication>
It does NOT do this on my local machine, just when I publish to my host. Does HangFire not recognize the authentication cookie that my main app provides when I login? I thought in general, the hangfire app doesn't require authentication, so what other configuration could be thinking that it does?
UPDATE 1:
I added the authorization filters per the hangfire docs, but the same thing happens. Here is my code in Startup.cs:
using Hangfire;
using Hangfire.Logging;
using Hangfire.Dashboard;
using Hangfire.SqlServer;
using Microsoft.Owin;
using OTIS.Web.AppCode;
using OTISScheduler.AppServ;
using Owin;
using System.Web.Security;
[assembly: OwinStartup(typeof(OTIS.Web.App_Start.Startup))]
namespace OTIS.Web.App_Start
{
public class Startup
{
public void Configuration(IAppBuilder app) {
app.UseHangfire(config => {
config.UseSqlServerStorage("DefaultConnection");
config.UseServer();
//Dashboard authorization
config.UseAuthorizationFilters(new AuthorizationFilter
{
Users = "USERA", // allow only specified users (comma delimited list)
Roles = "Account Administrator, Administrator" // allow only specified roles(comma delimited list)
});
});
LogProvider.SetCurrentLogProvider(new StubLogProviderForHangfire());
GlobalJobFilters.Filters.Add(new AutomaticRetryAttribute { Attempts = 0 });
var scheduleTasksInitializer = new ScheduleTasksInitializer();
scheduleTasksInitializer.ScheduleTasks();
}
}
}
UPDATE 2:
Per the more detailed instructions showing basic authentication, I also tried this...still no luck..redirects me to my app's login page.
config.UseAuthorizationFilters(
new BasicAuthAuthorizationFilter(
new BasicAuthAuthorizationFilterOptions
{
// Require secure connection for dashboard
RequireSsl = false,
SslRedirect = false,
// Case sensitive login checking
LoginCaseSensitive = true,
// Users
Users = new[]
{
new BasicAuthAuthorizationUser
{
Login = "MyLogin",
// Password as plain text
PasswordClear = "MyPwd"
}
}
}));

With the newer versions you should use IDashboardAuthorizationFilter. With the using statements, it will look like this:
using System.Web;
using Hangfire.Annotations;
using Hangfire.Dashboard;
namespace Scheduler.Hangfire
{
public class HangFireAuthorizationFilter : IDashboardAuthorizationFilter
{
public bool Authorize([NotNull] DashboardContext context)
{
//can add some more logic here...
return HttpContext.Current.User.Identity.IsAuthenticated;
//Can use this for NetCore
return context.GetHttpContext().User.Identity.IsAuthenticated;
}
}
}
then in the configuration section:
app.UseHangfireDashboard("/jobs", new DashboardOptions()
{
Authorization = new [] {new HangFireAuthorizationFilter()}
});

Finally got it working. I created my own AuthorizationFilter class (see below).
Then I passed that to the MapHangfireDashboard method in the Startup.cs Configuration method (see below that)
public class HangFireAuthorizationFilter : IAuthorizationFilter
{
public bool Authorize(IDictionary<string, object> owinEnvironment)
{
bool boolAuthorizeCurrentUserToAccessHangFireDashboard = false;
if (HttpContext.Current.User.Identity.IsAuthenticated)
{
if(HttpContext.Current.User.IsInRole("Account Administrator"))
boolAuthorizeCurrentUserToAccessHangFireDashboard = true;
}
return boolAuthorizeCurrentUserToAccessHangFireDashboard;
}
}
To map hangfire to a custom url and specify the AuthorizationFilter to use:
public void Configuration(IAppBuilder app) {
//Get from web.config to determine to fire up hangfire scheduler or not
app.UseHangfire(config => {
config.UseSqlServerStorage("DefaultConnection");
config.UseServer();
});
//map hangfire to a url and specify the authorization filter to use to allow access
app.MapHangfireDashboard("/Admin/jobs", new[] { new HangFireAuthorizationFilter() });
}

As designed I believe.
See the docs for the dashboard.
By default Hangfire allows access to Dashboard pages only for local requests.
Strangely enough I was dealing with this the other day and one thing to be aware of is that if you are using Autofac dependency injection then you need to make sure you configure items in the correct order. Specifically Hangfire after other authentication but also, in my case, MembershipReboot before the other OAuth stuff.
Took quite a bit of trial and error.
