      When connecting using ed25519, the client has the default plugin path wrong. If using a specific plugin path, in the config file or on the command line, it works, even if this is set in to the same value as the default.
      Extract from /etc/my.cnf.d/server.cnf

      plugin_load_add = auth_ed25519

      Create and grant access to a user:

      create user root2@'' IDENTIFIED VIA ed25519 USING PASSWORD('root2');
      grant all on *.* to  root2@'';

      Connect to MariaDB using ed25519 authentification:

      $ mysql -u root2 -proot2 -h
      ERROR 1045 (28000): Plugin client_ed25519 could not be loaded: /usr//usr/lib64/mysql/plugin/client_ed25519.so: cannot open shared object file: No such file or directory

      Note the path to the plugin, there is an extra leading "/usr" there. Setting the path to the correct one works fine:

      $ mysql -u root2 -proot2 -h --plugin-dir=/usr/lib64/mysql/plugin

      The above also work when setting the correct path in /etc/my.cnf.c/client.cnf or some other appropriate config file.
