Hello, I’ve found an apparent discrepancy between MySQL 5.6 and MariaDB 10.1. When you GRANT ALL PRIVILEGES on a DB to a user/host that is not in the mysql.users table, MariaDB 10.1 throws ER_PASSWORD_NO_MATCH, whereas MySQL 5.6 creates the user/host entry. Is this by design? I don’t see the behavior discussed at https://mariadb.com/kb/en/mariadb/grant/. Thank you for your time! Below I am including the client outputs for both servers. -Felipe Gasper Houston, TX -------------------------- Server version: 10.1.8-MariaDB-log MariaDB Server Copyright (c) 2000, 2015, Oracle, MariaDB Corporation Ab and others.
