I got SAML assertion from TrustAuthorityClient API. with below Public API code
securityToken = client.getSecurityToken("default", endpointURL, mexEndpointURL,
(java.lang.Object)ssoToken, SecurityMechanism.STS_SECURITY_URI,
(getServletConfig()).getServletContext());
But this is created with SunSTS.
When I test this Assertion to retrieve access token from SalseForce. it gives me invalid Assertion.
Is there any way retrieve SAML response from OpenAM for SalesForce?
When I test IDP initiates SSO with SalesForce. In Debug log I can see SAML Response is created for SSO.
How should I retrieve this SAML response from OpenAM?
You may need to grab the SAML Response via JavaScript at the front end. The full response will be in a SAMLResponse object after SSO, so your Assertion Consumer Service URL (SP SSO URL) that would receive this would need to check for that parameter, save it and somehow submit to SFDC for OAuth token exchange. Alternatively, take the Assertion from SunSTS and make your SAMLP Response wrapper yourself.
I believe this is due to SFDC implementing an earlier draft of the SAML 2.0 Bearer Assertion Profiles for OAuth 2.0 (see: https://datatracker.ietf.org/doc/html/draft-ietf-oauth-saml2-bearer-10).
The latest draft of that spec does not require the Response wrapper - likely just the Assertion itself from SunSTS will work, provided SFDC updates to support it.

I am setting up an IDP initiated SAML authentication flow
One of our clients will send an SAML assertion request to us by clicking a link within their internal system to access our application - so we act as the service Provider (we use Identity Server from Duende for Authentication)
We are looking at using ITfoxtec.Identity.Saml2.MvcCore library
AS we are going with an IDP initiated SAML flow, I wanted to check to know if
As an SP (Service Provider) do we only need to have an ACS end point for the incoming SAML Assertion. On receiving the Assertion we can process it to get the Claims we need and if it meets our requirements we can give the access to our application.
Do we need to send back any notification to the IDP that sent us the Assertion ?
Once verified after receiving the Assertion, do we set the access token in our Identity Server or do we get a token in, the assertion. We need periodically need to check if the user associated with the incoming Assertion is still authenticated in the IDP. Hence I was wondering if the IDP would issue a token with an expiration date/time, if not then would we have to initiate a new SP initiated SAML flow to check if the user is still authenticated with the Client IDP ?
DO we as an SP need to issue our own Access Token ?
For Logout, we only want to log the user out of our system (So remove our token if we issue one, we do not want to log out the user from their IDP?
Do we need to simulate login in our Identity Provider or will that happen automatically when we add the SAML2 to our Authentication method in our startup.cs
Do we use the ITfoxtec.Identity.Saml2.MvcCore library as we are using Duende IdentityServer in a .netCore 5.0 setup
is this possible with ITfoxtec library ?
services.AddAuthentication()
.AddSaml2(options =>
{
var spOptions = new SPOptions
{
EntityId = new EntityId("https://localhost:44373/Saml2"),
ReturnUrl = new Uri("https://localhost:44373"),
MinIncomingSigningAlgorithm = "http://www.w3.org/2000/09/xmldsig#rsa-sha1",
};
options.SPOptions = spOptions;
options.IdentityProviders.Add(new IdentityProvider(new EntityId("https://www.example.com/SSO/SAML/App"), options.SPOptions)
{
AllowUnsolicitedAuthnResponse = false,
MetadataLocation = "https://www.example.com/SSO/SAMLMetadata/App",
LoadMetadata = true,
});
});
Yes and you only need the ACS endpoint. You can also do logout if it is supported by the IdP.
No
You resave a SAML 2.0 token in the Assertion which has a lifetime. To check user state you either need the IdP to start a new IdP initiated login or you can start a SP initiated login, if supported by the IdP.
No. That do not has anything to do with the SAML 2.0 integration.
In IdP initiated scenarie the SP usually do not request the IdP to logout.
You need to simulate IdP initiated login, you can use this code sample.
You can integrate ITfoxtec Identity Saml2 into Duende IdentityServer but I do not have a sample on that.
If SAML Response has the status as "status:Responder",
According SAML spec:
urn:oasis:names:tc:SAML:2.0:status:Responder The request could not be performed due to an error on the part of the SAML responder or SAML authority.
We expect the IDP should send the error message along with the response.
In ADFS event viewer, we can find out why SAML request failed, however we don't have access to ADFS sever in production environment.
Is it possible to get the error message inside SAML response in case if the authentication fails?
I need a clarification about the terminology used in SAML2.0. I want to know if by "assertions" we mean a particular subcategory of SAML2.0 messages
or if we mean ALL SAML2.0 messages.
A SAML Assertion is an XML document that represents a set of claims (i.e. name/value pairs) about a user asserted by an Identity Provider. A SAML Assertion is not a SAML message itself, but it is contained in a SAML Response message. Apart from that there are other SAML messages such as SAML Requests, Logout Requests and Logout Responses that don't contain Assertions.
The SAML Response will be posted to the following url:
https://domain/sp/ACS.SAML2
But when I try to hit the url, I am not able to see the response.
Anything wrong in my approach?
Thanks & Regards,

A few things assuming you are setting up SAML 2.0 Web SSO Profile -
What do you mean you can't "see" the Response? Are you successfully logging into the IDP and having it redirect the Browser to the PF ACS URL?
With PingFederate, the application and protocol end-points are case sensitive. You should use http(s)://www.server.com:<PF runtime port>/sp/ACS.saml2. If you simply request this value from your browser with a GET request and no SAML data, PingFed will show you a generic error template page.
If you have successfully POST'd the SAMLResponse to the right endpoint, you will see the actual SAMLResponse logged in the /pingfederate/log/server.log.
I did SSO of OpenAM and SalesForce.com (SFDC)
I have installed OpenAM-Client SDK to retrieve SAML Assertion from OpenAM.
I used this assertion data to generate SAML response required for SalesForce. When I pass this data to SFDC. I got error message for SAML.
“Failed: Signature Invalid/Configured Certificate Mismatch”
I used same certificate and signature data which I got from OpenAM-client SDK public API assertion.
At time of SSO configuration with SDFC. I used default certificate (test cert) provided by OpenAM.
Is there any way to retrieve test certificate and its signature from OpenAM ?
Run one of the failing SAML assertions through the SAML Validation tool inside Single Sign-On Settings in SFDC; you should get a slightly more useful error. The most likely cause of this is that you have not uploaded the correct certificate to SFDC as part of your SSO setup. Make sure the "Identity Provider Certificate" section of "Single Sign-On Settings" matches the cert contained in the assertion.
