Hi
Thanks for reporting the issue, appears to be a bug in CXF or at the
lower level. I guess the KeyInfo is typically available on the WS path
hence the issue arises when it is not included.
I can suggest a workaround for now, till the problem has been resolved:
RequestAssertionConsumerService validateSamlResponseProtocol and
validateSamlSSOResponse methods are protected: I wonder if you can
override the method where the problem occurs and do the manual
validation for now or simply ignore the validation for now to get the
POC done.

Hi,
I am trying to implement a SAML Request Assertion Consumer Service
(RACS) with Apache CXF 2.7.7
Unfortunately the response of my Identity Provider does not include a
keyInfo (which is defined optional in the SAML specification).This leads
to an exception when processing the response, because CXF tries to load
a DOM for the keyInfo.
|java.lang.NullPointerException
at
org.apache.ws.security.saml.ext.AssertionWrapper.verifySignature(AssertionWrapper.java:536)
|
I have a valid keystore.properties file as well as the certificate on my
RACS site, but this does not chage the behaviour. Is this a bug in CXF
or did I miss something to set up for my RACS?
That's my current configuration
<bean id="consumerService"
class="org.apache.cxf.rs.security.saml.sso.RequestAssertionConsumerService">
<property name="stateProvider" ref="stateManager" />
<property name="enforceAssertionsSigned" value="false"/>
<property name="signaturePropertiesFile"
value="serviceKeystore.properties"/>
<property name="supportBase64Encoding" value="true" />
</bean>
And the response from my IDP is:
