MySQL connection using ODBC (5.1) with SSL

We've got a client application that connects to our online MySQL database (5.1.44-community-log) thru a ODBC connector (the server is a managed* dedicated webserver). This works very nice. However I can't get it to work using SSL. This is what I've done so far:

1. MySQL server

I've got the server manager* set up MySQL with SSL, this is 'proven by':

mysql> SHOW VARIABLES LIKE '%ssl%';

which results is this response:

+---------------+---------------------------------+
| Variable_name | Value                           |
+---------------+---------------------------------+
| have_openssl  | YES                             |
| have_ssl      | YES                             |
| ssl_ca        | /***/mysql-cert/ca-cert.pem     |
| ssl_capath    |                                 |
| ssl_cert      | /***/mysql-cert/server-cert.pem |
| ssl_cipher    |                                 |
| ssl_key       | /***/mysql-cert/server-key.pem  |
+---------------+---------------------------------+

Question: is the server configured right? I'm guessing it is...

2. Certificates

I've purchased real certificates (via my server manager). These are in the directory shown above. I've also downloaded the client-cert.pem, client-key.pem and ca-cert.pem from that directory.

3. MySQL user with REQUIRE [SSL|X509]

I've created a new user and then granted it access from any location (for testing) with SSL:

GRANT USAGE ON *.* TO 'somevaliduser'@'%' IDENTIFIED BY PASSWORD 'somevalidpass' REQUIRE X509 

4. ODBC Client

I've (just downloaded and) installed : mysql-connector-odbc-5.1.8-winx64.msi (64-bit) as my machine is a 64-bit Windows 7 machine (so that's not what's wrong).

And I've created a User DSN configuring it like this (no options set on tabs), which shows it connecting to the server (however not using - nor requesting to do so - SSL) successfully (using some valid user which doesn't requires SSL):

So the connection is able to establish, now try using SSL.

This is configured like this, which is like I've read about on MySQL.com. So I'm not 100% sure the options set are right.

As you can see it results in a error HY000. Turning on tracing (within the ODBC configuration) also shows this error.

Can anyone give me a hint on how to make this work? Even if you know about just a part of the solution?
