Good morning,

Whilst testing SSL of a MariaDB server version 10.4.8 running Linux from a
Windows 10 machine I noted that connection using MySQL client
(mysql-8.0.18-winx64) connects successfully, however connections with
MariaDB client (mariadb-10.4.8-winx64) fails.

In case of MariaDB I have downloaded the file (
https://downloads.mariadb.org/interstitial/mariadb-10.4.8/winx64-packages/mariadb-10.4.8-winx64.zip/from/https%3A//mirror.serverion.com/mariadb),
whilst for MySQL client I used (
https://dev.mysql.com/downloads/file/?id=490026).

Enter password: ********

To ensure that the SSL certificate is valid I also tried
"--ssl-mode=VERIFY_IDENTITY" with the mysql-8.0.18 client and it worked
fine.
