invalid destination error in Keycloak SAML integration

We are trying to integrate KeyCloak and external IDP using SAML protocol.
After the Keycloak and saml configuration, we tried to test. Keycloak is able to initiate a call to IDP and IDP is returning successful SAML response with requested nameId. But, Keycloak is throwing invalid destination error. Can anyone please help here?

WSO2 identity server - SAML2 Response Issuer verification failed

I am using the wso2 sample apps (saml2-web-app-pickup-dispatch and saml2-web-app-pickup-manager) to test single sign on through WSO2 identity server version 5.10.0
The deployment is fine and on clicking the application's login, it redirects to the WSO2 login page successfully.
User logs in successfully but receives error below.

} | Result : Success
Your Service Provider application(Pickup-Dispatch) is trying to verify if the received SAML response is issued by the expected SAML Identity Provider. WSO2 includes its ID in the SAML response's <saml:Issuer> tag.
Your application has a pre-configured entity ID for WSO2 in the saml2-web-app-pickup-dispatch.com/WEB-INF/classes/sso.properties file as below.
SAML2.IdPEntityId=localhost
Likewise, WSO2 IS populates its SAML response's issuer with the value you've configured in the Resident Identity Provider's Home Realm Identifier.
But you can override the Home realm identifier with the IdP Entity ID Alias of your Service Provider SAML configurations as below.
Bottom line, the Issuer ID of the SAML response should be the same as what you've configured in the Application as the IdP Entity ID.
Change either value to make them the same.

Signing auth request in shibboleth SP

I am using Shibboleth SP for SAML authorization.
Recently IdP has changed the configuration and it now requires to sign the AuthRequest.
IdP's metadata has following parameter
<md:IDPSSODescriptor protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol"
WantAuthnRequestsSigned="true"><md:KeyDescriptor use="signing">
SP's shibboleth2.xml file had following tag
<ApplicationDefaults entityID="...."
REMOTE_USER="eppn persistent-id targeted-id email Email FirstName LastName NameID">
After IdP enforced AuthRequest signing, we changed our shibboleth2.xml file as following
<ApplicationDefaults entityID="..."
REMOTE_USER="eppn persistent-id targeted-id email
Email FirstName LastName NameID"
signing="true" encryption="true">
Basically, I added signing="true" and encryption="true".
After that the new Metadata generated has following attribute in tag
<md:SPSSODescriptor AuthnRequestsSigned="1"
protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol
urn:oasis:names:tc:SAML:1.1:protocol urn:oasis:names:tc:SAML:1.0:protocol">
Earlier AuthnRequestsSigned="1" attribute was not present.
After this when I try to authenticate, it gives us following error,
<samlp:Status><samlp:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Responder"/>
<samlp:StatusMessage>Unable to verify the signature</samlp:StatusMessage>
</samlp:Status>
Question 1: Do I need to give IdP this new metadata?
Question 2: Any idea why this is happening?
Question 3: Do I need to change anything else in the configuration?
P.S. Before enforcing AuthRequest signing, it was working, so I don't think there is any other issue in configuration.
Here is the sample AuthRequest which goes
<samlp:AuthnRequest
AssertionConsumerServiceURL="https://...SP-host.../Shibboleth.sso/SAML2/POST"
Destination="https://...idp-host.../marrsso/idp/SSO.saml2"
ID="...some-id..." IssueInstant="2019-01-11T14:13:25Z"
ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Version="2.0"
xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol">
<saml:Issuer xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion">https://...entity-id.../shibboleth</saml:Issuer><samlp:NameIDPolicy AllowCreate="1"/></samlp:AuthnRequest>
I believe signing info should go here as part of request. As http request, it goes as GET request, is that correct?
When I see the request in network, I can see the Signature going as query param
The status code of the request is '200'
It is not unusual to send the signature as part of the query string. Its like a pre-signed URL.
Just enabling "signing=true" on SP should not change the key that
was originally generated. So re-sending the metadata is not a
requirement. Check with IdP if the SP's metadata was originally
imported in full or did they just add relying-party and other basic end
points to integrate, that might work just fine if request signing is
not required.
If IdP is not able to verify the signature then they must be missing
the certificate from SP. To be sure compare the two metadata files
before and after enabling signing and encryption, they should
match(specially around certificates) but for the additional attribute
that you had already identified. Resend the metadata otherwise.
No other configuration changes are required in this case.

SAML 2 Signature error in ADFS 2.0

In our SSO scenario, we are using ADFS 2.0 as IDP and Shibboleth as SP. It is an SP-initiated sign-on. After configuring, when I try to establish communication between Shibboleth and ADFS 2.0(throw browser redirect), ADFS 2.0 is throwing the below error.
The verification of the SAML message signature failed.
Message issuer: http://sampleserver/adfs/services/trust
Exception details:
MSIS1015: Server required signed SAML AuthenticationRequest but no signature present.
Event id - 320
Related Event id - 364
> Microsoft.IdentityServer.Service.SamlProtocol.SamlProtocolSignatureVerificationException:

> Microsoft.IdentityServer.Service.SamlProtocol.SamlProtocolService.Issue(IssueRequest
> issueRequest) at
> Microsoft.IdentityServer.Service.SamlProtocol.SamlProtocolService.ProcessRequest(Message
> requestMessage)
We haven't used any signature yet. I also have made SignedSamlRequest to false in ADFS properties. Signing of SAML at Shibboleth was also disabled.
I could not find any information in Microsoft site - apart from generic guide for this sort of errors.
Please advice on this error.
I was able to find the solution after a lot analysis. This is a Shibboleth configuration issue. In the application defaults section, the entity ID should be unique to the application.
ApplicationDefaults signing="false" entityID="http://URL of the protected Application "
REMOTE_USER="eppn persistent-id targeted-id"
Another variation of this error happens when sigining is set to true. It will result in Signature mismatch error in ADFS.

PingFederate SLO - Status Message: Invalid signature

After I invoke single-log-out (SLO), by calling 'GET' on https://[PingFederate Server Instance]:[Port]/sp/startSLO.ping, my PingFederate server begins making requests to my SP logout services. [I know this because I can see it happening in Fiddler.]
But when one my SPs invokes “https://<PingFederate DNS>:XXXX” + request.getParameter(“resume”); (per #Scott T.'s answer here), I get an error message:
Error - Single Logout Nonsuccess Response status:
urn:oasis:names:tc:SAML:2.0:status:Requester Status Message: Invalid
signature Your Single Logout request did not complete successfully. To
logout out of your Identity Provider and each Service Provider, close
all your browser windows. Partner: XXXX:IDP Target Resource:
http://<domain>/<default SLO endpoint>
My Questions:
What is this error message referring to?
How can I resolve this error condition?
This error is likely due to a mismatch in configuration between IdP and SP. The signing keys/certificate for SAML messages used at one end, must match the verification certificate at the other end. Check your Credentials configuration on your connection for both IdP and SP. See this section in the PingFederate Administration Guide for some details.
