I was using Spring Security SAML with Spring Boot using this template. However, after the certificates for my IDP were updated, the application stopped working and I realized that I was using Metadata interoperability profile (MetaIOP) for signature validation. I believe that since my SP is still using the old IDP metadata XML, the signature verification is failing and I am getting the following error:

I tried fixing this by importing the signing certificate to keystore and adding the following lines in configuration:
// Metadata Resolver
@Bean
public MetadataCredentialResolver metadataCredentialResolver() throws MetadataProviderException, URISyntaxException {
MetadataCredentialResolver metadataCredentialResolver = new MetadataCredentialResolver(
metadata(), this.keyManager
);
metadataCredentialResolver.setUseXmlMetadata(false);
return metadataCredentialResolver;
}
and
// Setup advanced info about metadata
@Bean
public ExtendedMetadata extendedMetadata() {
...
extendedMetadata.setSecurityProfile("pkix");
extendedMetadata.setTrustedKeys(null);
return extendedMetadata;
}
But it seems to still not be working with the same traceback. I am even more confused by the fact that log message on Line 1 says "SAML protocol message was not signed". Why does it evaluate trust then?
