Caused by: sun.security.validator.ValidatorException: PKIX path building failed - spring

Question

Thanks Vladimir. After having included my second ADFS configuration and tried to access the same under the metadata page, I got the following exception in the app server console:
Error retrieving metadata from //<adfs_server2>/FederationMetadata/2007-06/FederationMetadata.xml

I do added the corresponding FederatedMetadata.xml file in the classpath as well.
My Configuration in securityContext.xml file looks like this:

Your system complains that it's unable to verify the certificate presented by the HTTPS endpoint of your ADFS. You can find details on how to configure trust for such endpoints in the Spring SAML manual, see chapter 7.2, section HTTP-based metadata provider with SSL, it says:
By default, loading of metadata using the HTTP-based provider over
HTTPS performs trust verification configured in your JDK. In case
you'd like to use certificates in your keyStore, add the following
bean which changes the socketFactory used by the HTTP Client:
<bean class="org.springframework.security.saml.trust.httpclient.TLSProtocolConfigurer"/>
The TLSProtocolConfigurer instantiates TLSProtocolSocketFactory and
registers is as a default socket factory for https protocol inside the
HTTP Client used for metadata loading. The socket factory uses all
public certificates present in the keyStore as trust anchors for PKIX
validation. The used keys can be constrained with property
trustedKeys.
So you should simply import certificates used by the ADFS into your samlKeystore.jks and configure the above mentioned bean. Details on extracting the certificates and importing them can again be found in the manual.
