Thanks for your feedback! Actually it's the other way round. Validation succeeds with the *new* library (libssl.so.1.1), and fails with the *old* one (libssl.so.1.0.0). This is true with the openssl verify program as well: `openssl verify` succeeds for OpenSSL 1.1.0f, and fails for OpenSSL 1.0.1g.
Hence, if at all, verification requirements must have been lowered in the new OpenSSL version. I'm just about to look for a list of criterias a certificate has to pass in order to validate successfully in the two OpenSSL versions.
