Good morning, i need help in order to grant a monitor user to check the slave status in a master-salve replication. This is the error and the activity done to solve without success, the issue:

MariaDB [(none)]> show slave status\G

ERROR 1227 (42000): Access denied; you need the SUPER,REPLICATION CLIENT privilege for this operation

MariaDB [(none)]> exit

Bye


MariaDB [(none)]> GRANT SUPER, RELOAD, PROCESS, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO zabbix@'%';

Query OK, 0 rows affected (0.00 sec)

- Login with user zabbix:

mysql -S /mysql/mysql.sock -u zabbix -p

It is a bug of older version? If i do the same on MySQL 5.7 the monitoring user can check the slave status.
