connect MVC 5 app to ADFS 2.0

I have created fresh MVC 5 app and installed nuget package.
WsFederation in Startup.Auth is configured as follows:
app.UseWsFederationAuthentication(wtrealm: "MyRealm",
               metadataAddress: "https://myADFSInstanceHost/FederationMetadata/2007-06/FederationMetadata.xml");  
Federation button at login page works fine. ADFS login page is achievable, i can log in there. But when callback to mvc app is performed, in ExternalLoginCallback controller AuthenticationManager.GetExternalLoginInfoAsync() returns null.
Adfs itself works ok, i can authenticate against it using pure WIF VS template.
Please suggest what could be wrong.. Thanks

i am totally confused.. What needs to be used in order to connect mvc5 web app to ADFS 2.0 via OWIN/Katana? UseWsFederationAuthentication or UseActiveDirectoryFederationServicesBearerAuthentication ( from )? Could some one route me to a working sample of such integration?

UseWsFederationAuthentication is for interactive web pages (redirects to a login page, etc.). UseActiveDirectoryFederationServicesBearerAuthentication is for API access.

You can use Fiddler, Netmon, etc., to look at the request and response headers to see what happens. You're primarily looking for Set-Cookie and Cookie headers that preserve the identity across requests.

OK, i am using UseWsFederationAuthentication, as i need to be redirected to adfs login and then redirected back to my app.
Here is sequence of request/response i have:
0)"Federation button" does postback to my app, ExternalLogin controller: https://localhost/Account/ExternalLogin.
Controller sends to browser Transport header. Location is
1)After successful authentication at adfs login page, it sets several cookies:
and does POST to https://localhost/ (as it is configured at ADFS as WS-Federation end point).
POST contains 3 hidden fields: wa, wresult, wctx.
3) https://localhost/ returns to browser Transport header: Location: /Account/ExternalLoginCallback.
4) In ExternalLoginCallback controller AuthenticationManager.GetExternalLoginInfoAsync() returns null.

According to this, i guess, 3) is wrong. Data posted from adfs page are getting lost between transport from localhost to localhost/Account/ExternalLoginCallback.
If it is really wrong, how to configure properly callback URL?

There should be new Set-Cookie headers with step 3. Sharing your Startup may help identify what's wrong with your cookie setup.

here it is:
public void ConfigureAuth(IAppBuilder app)
            app.UseCookieAuthentication(new CookieAuthenticationOptions
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Account/Login"),
                Provider = new CookieAuthenticationProvider
                    OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
                        validateInterval: TimeSpan.FromMinutes(30),
                        regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
            app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));

            app.UseWsFederationAuthentication(wtrealm: "http://localhost:8099/",
              metadataAddress: "https://myadfsendpoint/FederationMetadata/2007-06/FederationMetadata.xml");

update: step 3 sends this cookie

is this what is required at step 4 (callback controller)?

update2: steps 3 and 4 sends .AspNet.ExternalCookie. Tratcher, according to another your post it's generated by Katana.
But still i can't get login info from GetExternalLoginInfoAsync()

I have similar situation as well Any chance you have the solution?

I have found a solution for my case. It was my fault, one of relying party at ADFS was configured wrong. And of cause this party i was trying to use for MVC app authentication. In particular, claims rules were not set well. Would be nice to have more detailed exceptions from Katana/Ws-Federation Plug in. When GetExternalLoginInfoAsync just return null, there is no way to debug.

Woahh its seem very hard to debug:( I am using Azure Active Directory so i am not sure if i can find out what config can be done:(

Finally with lots of try and debug. I can use my now and the solution is to remove this line out of StartUp. This allow me to login using Microsoft Account and OpenID at the same time. In my chase OpenID is Azure Active Directory.
Hope this helps
