Vault users getting deleted after 60 seconds in MariaDB

Mariadb is deleting automatically the users created via Vault, using the command vault read database/cred, after exactly 60 seconds. Not happening when I create them via phpmyadmin, terminal or any other method. It’s not a Vault issue because I have tried changing password of the vault user after it creates the user and the deletion still happens at 60 secs.Any ideas?

Can you share the Vault config for the database secrets engine and the role you are using?
