I managed to solve the issue.
I downloaded the MariaDB window version (10.0.20) that corresponded to the version on our server and replaced the libmysql.dll and dialog.dll files that were shipped with HeidiSQL with the ones from MariaDB.
Not sure if it will introduce any new problems, but at least I can login now.
