mysqldump Error 1045 Access denied despite correct passwords etc

Question

This is a tricky one, I have the following output:

mysqldump: Got error: 1045: Access denied for user \'root\'@\'localhost\' (using password: YES) when tr

Answer 1

Mysql replies with Access Denied with correct credentials when the mysql account has REQUIRE SSL on

The ssl_ca file (at a minimum) had to be provided in the connection paramiters.

Additional ssl parameters might be required and are documented here: http://dev.mysql.com/doc/refman/5.7/en/secure-connection-options.html
