    saml2:     # ADDED to support SAMLv2 authentication to IDP.

              credentials:
                - private-key-location: classpath:saml/private.key
                  certificate-location: classpath:saml/public.cert

private.key and public.cert will be used to sign requests to the relyingparty. 
Also, the public.cert will be included in the generated metadata: http://localhost:8081/saml2/service-provider-metadata/mock-idp

To generate private.key and public.cert :

> openssl req -x509 -newkey rsa:2048 -keyout private.key -out public.cert -days 365 -nodes -subj "/CN=localhost"


The file idp-public.cert, was copied from the <mock-idp>\certs
<mock-idp> is a project for testing SMLv2 auth. Look in src\main\mock-idp
