We are getting a warning stating "Detected excessive grant privileges". Our DB Admin reviewed the setup instructions regarding creating a user under step 5; https://fivetran.com/docs/databases/mariadb/setup-guide. We removed a permission named "BINLOG MONITOR" and the connector immediately began failing with "insufficient_user_permissions" errors. It appears this is related to MariaDB version 10.6 where the new permission was added and the permission checks in Fivetran should be updated to include them.
