> Take 2 certificate files: cert.pem and truststore.pem
> cert.pem has 2 certificates in it:
> A cert for that node (with CN="hostname", and signed by CN=CertToolkitIntCA)
> And the intermediate CA cert (with CN=CertToolkitIntCA, and signed by CN=CertToolkitRootCA)
> truststore.pem has 1 certificate in it:
> A cert which is the root CA (with CN=CertToolkitRootCA, self-signed)
> This format of certificates don't seem to verify on the OpenSSL command line but works with Thrift. This also doesn't work with KRPC.
> Workaround for this issue w/ KRPC turned on:
> If we move the second certificate from cert.pem (CN=CertToolkitIntCA) into truststore.pem, then this seems to work.
> We'll need to dig into whether this is a PEM file format issue, or a KRPC issue. But the above workaround should unblock us for now.
