mariadb アクセスが centreon@localhost に拒否されました

Question

Centreon を新しいサーバーとバージョンに移行しようとしているのですが、debian11 の syslog にこのエラーが表示されます。

mariadbd[1640]: 2023-10-20 11:13:52 13360 [Warning] Access denied for user 'centreon'@'localhost' (using password: YES)

権限を付与しようとしました

hMariaDB [(none)]> SHOW GRANTS FOR 'centreon'@'localhost';

しかし、まだこのエラーが発生します。どうすれば修正できますか?
