The authentication itself is delegated by DBI to DBD::MariaDB, which (I guess) in turn delegates that to the MariaDB database drivers. Two issues I find on the interwebs suggest that the MariaDB client packages do not necessarily include the appropriate client authentication plugin library ( Askubuntu, Github ).

So maybe explicitly installing the mariadb client (instead of only DBD::MariaDB) via your OS package manager helps provide the appropriate plugin?
