mysql2 never explicitly sets MYSQL_OPT_SSL_VERIFY_SERVER_CERT, so it inherits whatever default mariadb-connector-c compiles in. Starting with connector-c 3.4.0, that default flipped to verify the server cert (see mariadb.com/kb/en/mariadb-connector-c-3-4-0-release-notes), which breaks ccdb connections for deployments that don't configure a CA cert (see brianmario/mysql2#1379). Building with -DDEFAULT_SSL_VERIFY_SERVER_CERT=OFF restores the pre-3.4 default of not verifying, while leaving explicit TLS configuration untouched.
