How to set x509 on a QSqlDatabase Connection?

[m3rlin]

Indeed, the referencing doesn't matter. But I did prove the following:
1. The path to the certificates is correct.
2. The way they are used in mysql_ssl_set() is correct.
3. That the program is actually using an SSL connection:
a. because MySQL Server accepted the connection, while it was configured to ONLY accept user "test", if he could supply a valid x509.
b. because the SHOW STATUS LIKE 'Ssl_cipher' replies with the cipher used, and it ONLY does that when a SSL connection is established.
c. becuase WireShark reports SSL trafic on port 3306
4. That somehow setting the QSqlDriver or QMySQlDriver handle with my code doesn't work via mysql_ssl_set().

Whom should I contact for an explanation? Where can I find documentation about the underlying structures? Maybe anyone reading this has a similar problem and found a solution? Or is it a Qt shortcoming in arguments that can be specified for QSqlDriver?

Not necessarily but that's a minor problem.

4. That somehow setting the QSqlDriver or QMySQlDriver handle with my code doesn't work via mysql_ssl_set().

There is no such handle. There is the MYSQL structure which is a MySql handle which is exactly the same what you are using in your test program.

Whom should I contact for an explanation?

What kind of explanation?

Where can I find documentation about the underlying structures?

Qt's SQL drivers are documented in Qt's docs.

Or is it a Qt shortcoming in arguments that can be specified for QSqlDriver?

Yes, and you need to work around that by calling mysql_ssl_set at the right moment (like directly after calling addDatabase())
