I am trying to set up Keycloak as IdP and use it for SSO. The first re-direct (from the application login url to keycloak) works fine, but then, after entering the user credentials I get an "invalid signature" error from the application.
I have checked the SAML response (from keycloak to the application) and I can see that keycloak adds a weird escape character
in the certificate and signature value.
Here is part of the SAML response
<dsig:Signature xmlns:dsig="http://www.w3.org/2000/09/xmldsig#">

Why does it have to truncate the signature and add the
escape code? Is there a way to change this?
I am sure that this is the error that is preventing the application from reading the response.
Thank you in advance

I am trying to enable SSO capabilities for Apache Zeppelin, using Apache Knox, which is configured to redirect auth requests to a Siteminder IdP.
The issue I am having is related to the NameID format configuration, and the signing configuration.
No matter what I configure in the sp/idp metadata, the NameID format used is
urn:oasis:names:tc:SAML:2.0:nameid-format:entity
And the requests are always being sent with Signed requests set to true.
My SP configuration is as follows:
<EntityDescriptor xmlns="urn:oasis:names:tc:SAML:2.0:metadata" entityID="https://knox.test.com/gateway/knoxsso/api/v1/websso?pac4jCallback=true%26client_name=SAML2Client">
<SPSSODescriptor AuthnRequestsSigned="false" WantAssertionsSigned="false" protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol urn:oasis:names:tc:SAML:1.1:protocol http://schemas.xmlsoap.org/ws/2003/07/secext">
<NameIDFormat>
urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified
</NameIDFormat>
<SingleLogoutService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="https://knox.test.com/gateway/knoxsso/api/v1/websso?pac4jCallback=true%26client_name=SAML2Client"/>
<AssertionConsumerService
Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" index="1" isDefault="true" Location="https://knox.test.com/gateway/knoxsso/api/v1/websso?pac4jCallback=true%26client_name=SAML2Client"/>
</SPSSODescriptor>
I activated a SAML tracer and attempted the logon user journey. The AuthNRequest being sent to the Siteminder IdP based on this configuration looks like this:
<saml2p:AuthnRequest xmlns:saml2p="urn:oasis:names:tc:SAML:2.0:protocol"
AssertionConsumerServiceURL="https://knox.test.com/gateway/knoxsso/api/v1/websso?pac4jCallback=true%26client_name=SAML2Client"

<saml2:Issuer xmlns:saml2="urn:oasis:names:tc:SAML:2.0:assertion"

>https://knox.test.com/gateway/knoxsso/api/v1/websso?pac4jCallback=true%26client_name=SAML2Client</saml2:Issuer>
I can see a signature value in the Parameters section of the request, which is why I'm assuming that the AuthNRequest is signed (though my understanding of this is minimal, so that could be a wrong assumption!).
Can anyone help explain why the NameIDFormat is coming through as entity, as opposed to unspecified?
Does Apache knox support SAML1 protocols?
Thanks in advance!
You mentioned NameID format to be urn:oasis:names:tc:SAML:2.0:nameid-format:entity in your post but in the code you pasted it is urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified, just a copy paste error ? Looks like protocolSupportEnumeration is also referencing SAML 1 protocol. Knox uses Pac4J under the hood which does not support SAML 1, this might be the reason.
I have a question about SAML markup. I'm currently working on a project where I need to integrate a third-party application to work with windows ADFS.
I see in the sample SAML file they have sent me the makeup always starts with <saml:....>
for example:
<saml:Assertion ...>
..
</saml:Assertion>
<saml:Subject>
</saml:Subject>
<saml:Conditions
</saml:Conditions>
<saml:AuthnStatement
</saml:AuthnStatement>
...... etc
While in Windows ADFS, the SAML file that gets generated doesn't have this saml append in it's response markup.
<Assertion ...>
..
</Assertion>
<Subject>
</Subject>
<Conditions
</Conditions>
<AuthnStatement
</AuthnStatement>
i'm getting {"non_field_errors":["invalid_response"]}after ADFS login, so I'm trying to isolate what causing this to happen. cloud this be a reason for it not to work?
Check out my channel which has more than 10 videos explaining everything related to ADFS -https://www.youtube.com/channel/UCO-AQkOHCYZias9arGmQtOA

*The sample which you have received from your team, is a SAML 1.0 token, for which the saml was supposed to be used as prefix.
Below mentioned is one example. *
*But, if you request SAML 2.0 token, this prefix will not be available. *
I've installed Hybris 6.4 and I want to make use of its secured RESTful access to all Hybris models, that comes with the platformwebservices.
In order to have access to the REST API, i.e. requests like http://localhost:9001/ws410/rest/countries, I need to configure the OAuth 2.0
I think, I need to understand what values I need to provide in the headers:
client_id=...&client_secret=...&grant_type=...&username=...&password=...?
To test, you can simply use basic authentication with username/password (admin/***). In postman select basic authentication with username and password (Update request).
Find sample request from wiki.
Webservices are getting authenticated using the configuration in security-spring.xml.
<oauth:client client-id="client-side" resource-ids="hybris" authorized-grant-types="implicit,client_credentials"
authorities="ROLE_CLIENT" secret="secret" redirect-uri="http://localhost:9001/rest/oauth2_implicit_callback" />
<oauth:client client-id="mobile_android" resource-ids="hybris"
authorized-grant-types="authorization_code,refresh_token,password,client_credentials" authorities="ROLE_CLIENT" secret="secret"
redirect-uri="http://localhost:9001/rest/oauth2_callback" />
<oauth:client client-id="trusted_client" resource-ids="hybris"
authorized-grant-types="authorization_code,refresh_token,password,client_credentials" authorities="ROLE_TRUSTED_CLIENT"
secret="secret" />
These are the different client-id and secret codes available by default.
I have an Identity Provider that I wish to preform SSO against using SAML 2.0
I'm using https://github.com/KentorIT/authservices
The IdP configuration is :
Entity Id: https://xxx.yyy.com/auth
Assertion Consumer Service URL: http://zzz:1111/AuthServices/Acs
I have created a self-signed certificate and added it to the local project.
The local configuartion:
<kentor.authServices entityId="https://xxx.yyy.com/Files/Metadata/IdP/Saml"
returnUrl="http://localhost:8585/">
<identityProviders>
<add entityId="https://xxx.yyy.com/"
signOnUrl="https://xxx.yyy.com/Saml/Login.aspx"
allowUnsolicitedAuthnResponse="true" binding="HttpRedirect">
<signingCertificate fileName="~/App_Data/SelfSignedCertificate-2016-01-10-22-37.cer" />
</add>
</identityProviders>
<federations>
<add metadataLocation="http://localhost:52071/Federation" allowUnsolicitedAuthnResponse="true" />
</federations>
</kentor.authServices>
I will appreciate any kind of help as i'm stuck with this.
Thanks
Gilad
The first entityId, in the kentor.authServices root element should be the identifier you use for your site. Typically http://zzz:1111/AuthServices, which is the ACS url minus the last part.
The signingCertificate within the identityProviders/add element should not be your own certificate, but the certificate that the Idp uses to sign messages.
The federations element should be completely removed. It points to the local development environment, that it looks like you've copied the config from.
I'm not able to make a secured ECP AuthnRequest to my Shibboleth IdP. I've got a small proof of concept SP running which is based heavily on the Spring SAML extension sample app. My SP metadata was generated using the Spring SAML extension sample app's metadata generator. The signing key being used is the apollo one included with the sample app samlKeystore.jks key store, all of which is also in my own small SP app.
In my SP metadata, I have the AuthnRequestsSigned attribute set to true like so :
<md:SPSSODescriptor AuthnRequestsSigned="true" WantAssertionsSigned="false" protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol">
If I set AuthnRequestsSigned to false and make the ECP SOAP POST to the IdP, it works just fine. I get the proper SOAP message back from the IdP. But if that value is true, I get a non-descriptive error message:
<env:Fault>
<faultcode>env:Client</faultcode>
<faultstring>An error occurred processing the request.</faultstring>
<detail/>
</env:Fault>
I look in the Shibboleth (IdP) logs and see:
Attempting to extract credential from an X509Data
Found 1 X509Certificates
Found 0 X509CRLs
Single certificate was present, treating as end-entity certificate
Credentials successfully extracted from child {http://www.w3.org/2000/09/xmldsig#}X509Data by provider org.opensaml.xml.security.keyinfo.provider.InlineX509DataProvider
A total of 1 credentials were resolved
This displays twice in the log for my transaction. My assumption is because it's finding the certificate in the request and in my SP metadata. Further down in the log during this same transaction I see this followed by a stack trace:
Attempting to validate signature using key from supplied credential
Creating XMLSignature object
Validating signature with signature algorithm URI: http://www.w3.org/2000/09/xmldsig#rsa-sha1
Validation credential key algorithm 'RSA', key instance class 'sun.security.rsa.RSAPublicKeyImpl'
Signature did not validate against the credential's key
Signature validation using candidate validation credential failed
Signature did not validate against the credential's key
I compared the certificate that is in the ECP POST AuthnRequest to the one in my SP metadata used for "signing" and they are the same. So I'm not sure why I'm getting this error.
My understanding is that the IdP will take the certificate found in the <ds:X509Certificate> tag of the request (which is the public key) and make sure that's the same one defined in the SP metadata. Then use that cert to verify the signature value which is also in the request in the <ds:SignatureValue> element. If it validates then it moves forward with the AuthnRequest. Is this accurate?
What piece am I missing?
Update 1: I've added the logging lines as suggested and here's all it shows for the ECP requests:
signatureMethodURI = http://www.w3.org/2000/09/xmldsig#rsa-sha1
jceSigAlgorithm = SHA1withRSA
jceSigProvider = SunRsaSign
PublicKey = Sun RSA public key, 2048 bits
modulus: <long value here>
public exponent: 65537
Signature verification failed.
One thing of note, if I make a request to my SP via a browser and I'm not signed in, I get redirected to my IdP login page as expected. I check the IdP logs and see that that request was also signed and it validates. I looked at the form data sent to the IdP from the SP and see that AuthnRequest is also signed using the same certificate but the SignatureValue value are different of course. That non-ECP request data XML looks very similar to the ECP request SOAP XML yet the ECP one fails.
UPDATE 2: I'm using spring-security-saml-1.0.0.RELEASE, and Shibboleth IdP v2.4.0. Here's a sample message I'm sending to the IdP:

I'm pretty much just copying the response from the initial PAOS request to the SP (Spring SAML), removing the header innards, and sending that along to the Shibboleth IdP. The headers that I send are:
Content-Type: text/xml
Authorization: Basic <base64 encoded credential string here>
Update 3: Signed non-ECP AuthnRequests validate just fine. So it's only SOAP ECP AuthnRequests to the IdP where the signature fails. Any ideas?
Update 4: Still can't get this working. Any help would be appreciated.
