Hello,

We are connecting to Azure MySQL database using redirection https://docs.microsoft.com/en-us/azure/mysql/howto-redirection to be able to improve performance.
DB connection is configured as follow:

 'DB' => [
        'Connections' => [
            'Default' => [
                'charset' => 'utf8',
                'dbname' => getenv('DB_NAME'),
                'driver' => 'mysqli',
                'host' => getenv('DB_HOST'),
                'password' => getenv('DB_PASSWORD'),
                'user' => getenv('DB_USER'),
                'driverOptions' => [
                    'flags' => MYSQLI_CLIENT_SSL,
                ],
            ],
        ],
    ],

mysqlnd_azure.enableRedirect is on, but SSL option is not set in connection string. Redirection is only possible with SSL.

I've investigated \Doctrine\DBAL\Driver\Mysqli\MysqliConnection::__construct and for BE is all right. All parameters are set in constructor. But or the FE dbname, host and driverOptions are not set. Why so?
