@mlindegarde Thank you. Over the weekend I did test that once I accessed the link the prover was added. Thanks a lot for all your help!

Hi, I am wondering if there is any way to disable automatic metadata refresh?

I have a situation where a metadata document is held in file storage. Retrieval of this document is relatively expensive. Once the document reaches it's refresh time, the system will continually attempt to re-load it, even though the document will not change. In this instance, I would like to disable the automatic refresh feature. If I release all references to the IDP, the requests still seem to get generated. I am assuming there is no Notification Hook I could use here?

I am also finding that the IDP is still active when the ValidUntil date is passed.

@AndersAbel I'm having a problem with HTTPS vs HTTP. When I run my identity server in a container locally I get the following:

[16:05:57 Debug] Sustainsys.Saml2.AspNetCore2.Saml2Handler
Expanded Saml2Url
  AssertionConsumerServiceUrl: https://localhost:5001/Saml2/Acs
  SignInUrl: https://localhost:5001/Saml2/SignIn
  LogoutUrl: https://localhost:5001/Saml2/Logout
  ApplicationUrl: https://localhost:5001/

The AssertionConsumerServiceUrl is properly using https.

When I run the container in Azure the AssertionConsumerServiceUrl is http://auth.my-company/Saml2/Acs. It's using http instead of https. I'm not sure why that is.

I found it... saml2Options.SPOptions.PublicOrigin = new Uri(config.Settings.BaseUrl);

I am trying to use the MVC integration in my MVC app and read all the docs and looked at everything I can think of but for some reason the Saml2Controller does not seem to be loaded or responding to anything I get a 404 not found when accessing anything off that controller (e.g. https://localhost:44301/Saml2/Acs. This must be something simple that I am missing. My routing is just default MVC routing. No filters, just default. Added the sustainsys.saml.mvc package and set the configuration as in the docs, but just doesn

I am still waiting for this

@AndersAbel PLEASE

whenever i am hitting my url https://test.xyz.com it redirects me to ADFS, and there after putting credential SAML2 HTTpModule again redirecting multiple times with different saml request and finally it is giving error as i have written above

@anarshadali I recently had to deal with this problem. Whenever you get back the status code Responder that means that the identity provider you are using did not like the SAML2 request it received. This is almost always because of a configuration issue.

Unfortunately I cannot remember exactly which value was improperly configured.

If you've recently changed configuration values, make sure that you clear all related cookies (the cookie for the IDP, your site, your identity server, etc...). If you have a cookie holding an old value that no longer matches up with what your IDP expects, that could also cause this problem.

Md. Arshad Alam

@anarshadali

Thanks @mlindegarde for your kind response. yes i have changed the configuration, but also i am sure i have cleaned all cookies and session even history as well. but no success.

i asked for adfs log as well from server team.
in the mean while if by chance you get remember the configuration part then please let me know.

thanks once again

Mike Lindegarde

@mlindegarde

@anarshadali Reading through my notes, I believe my problem ended up being that I had an old cookie using the wrong entity id after making changes to the IDP. I'll be curious to see what you find in the ADFS log. In my case I didn't realize the problem until I decided to try using Edge (a browser I don't normally use) instead of Chrome. That's how I narrowed my problem down to a cookie issue.

Hi everyone i am getting below error, please suggest i am using correct certificate files.

The signature verified correctly with the key contained in the signature, but that key is not trusted.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: Sustainsys.Saml2.Exceptions.InvalidSignatureException: The signature verified correctly with the key contained in the signature, but that key is not trusted.

//
even after using correct certificate file (private and public key i am getting this above error.

is there any way to resolve this or stop validating this part.

Md. Arshad Alam

@anarshadali

Hi @AndersAbel , Regarding above certificate validation issue.

I am getting response successfully from ADFS server (as i checked in one of the chrome extension) but due to certificate validation method called i am not getting response in thread principle claims.

please suggest me that how can i resolve this.
Can i stop certificate validation part by changing in some configuration.

using latest stable version of SAML.HttpModule.

I will be grateful if you will revert me on my issue.

Anders Abel

@AndersAbel

@anarshadali No, you're not using the correct certificate. If you check in the chrome extension you'll see that the certificate that is embedded in the signature in the incoming response/assertion is not the one you have configured for the Idp.

@anarshadali

Hello @AndersAbel ,

First of all, it's a very kind of you that you given time to reply me.

But as I have matched again both the public certificate and the token signing certificate The IDP Certificate which is coming in response from ADFS are identical to what i have configured in my application as an idp certificate as you can see in the image above.

The only things new i have found is my ADFS contains 2 token signing certificate 1 is newer which i am using and other is older one which is not in use anymore.

Please help me if there is any suggestion or guidance.
(i am using chrome 3rd party extension named "SAML message decoder")

Hi, am I correct in my assumption that a new claim is added to the claims identity for each additional attribute in the saml response?

And so, if the IdP adds an attribute named "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name", that will create a claim with the same name and ,in turn, map to User.Identity.Name?

It certainly looks that way from my testing, but I want to confirm because our app will possibly be integrating with numerous customer IdPs and I want to make sure I have standard setup instructions that we can give out.

@anarshadali

Is there not any way to control manually or to redirect to some custom page of alternate login if due to any reason user will not able to logged in on runtime.
I want my user will able to become login using manual login form, in case any issue occurred during authentication from either ADFS side or from Application side (instead of throwing YELLOW error page).

Brief:
on application 1st hit i want to redirect my user to ADFS, Whether ADFS do not responded OR ADFS do respond but SAML response was not able to parse from Sustainsys SAML httpmodule OR SAML response Status code is something other than success then in any such scenario i want user get auto redirect on to some other existing login page.

i am using
SAML2.HTTPModules
Asp.Net, C#, and 4.6 framework of dot net

Hi, I have an Idp that wants to use Idp Initiated Sign on and pass in a relaystate for a redirect url after login. From my understanding this Saml2 handler does not support that, is that correct?

The handler does support that. But it needs to be enabled in the settings.

There is no fix for that currently. There is an open issue, please see discussion in there.

I want to implement SAML2 in our existing ASP.NET MVC (framework 4.6.2) application with ADFS 2016. As the Sustainsys.Saml2.MVC is not supporting 4.6.2 framework. So I tried to implement it with Sustainsys.Saml2.Owin package but it is not redirecting to ADFS login page. Is any one has working example which uses Sustainsys.Saml2.Owin with ADFS?

Sure, I can point you in the right direction...

Hi Guys, I used this code as a sample for my project. It works for old IDP and after I add new, it also works. But when I want to delete it we getting Idp as null from the GetProvider method, as result in the method ValidateSignature, we getting a null reference error. Prety same as here Sustainsys/Saml2#1046
Any advice, how to resolve it?

builder.AddSaml2(
    saml2Options =>
    {
        saml2Options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;

        saml2Options.SPOptions.EntityId = new EntityId(config.Saml2.ServiceProviderEntityId);
        saml2Options.SPOptions.ServiceCertificates.Add(certificate);

        saml2Options.Notifications.SelectIdentityProvider =
            (id, data) => GetProvider(identityProviderStore, id, data, saml2Options, logger);

        saml2Options.Notifications.GetIdentityProvider =
            (id, data, options) => GetProvider(identityProviderStore, id, data, options, logger);

        saml2Options.Notifications.AcsCommandResultCreated =
            (commandResult, response) =>
            {
                if (commandResult.Principal.Identity is ClaimsIdentity identity)
                    identity.AddClaim(new Claim("in_response_to", response.InResponseTo.Value));
            };
    });

@robert_p_king_twitter

In the docs, it says about service certificates, "Specifies the certificate(s) that the service provider uses for encrypted assertions (and for signed requests, once that feature is added). If neither of those features are used, this element can be omitted."

What does it mean by "once that feature is added"?

Also, does anyone have an example of how to add a certificate in code (not using .config)?

Anders Abel

@AndersAbel

@robert_p_king_twitter That looks like stale docs. Signed requests are supported. See https://stackoverflow.com/questions/67230532/cannot-create-sustainsys-certificateelement-from-x509certificate2-object-to-upda

Rob King

@robert_p_king_twitter

@AndersAbel yeah I actually found that exact post a bit earlier. It helped me get further along. I think my issue is largely around the actual certs I'm using.

Rob King

@robert_p_king_twitter

Can I get a brief explanation of how multiple SP or IdP certificates are used once loaded?

Scenario: we want to load up a certificate and at a later date, its successor to make a seamless transation with no downtime or synchronisation with the IdP. I can load these easily into the ServiceCertificateCollection and they are both emitted through the SP metadata fine.

Question: given I have two certificates loaded, when signing the request, which certificate will Sustainsys use?

Likewise, when an ACS is returned from the IdP and we have two certificates of theirs loaded, does the middleware just look a matching cert?
