Plesk 12.x / Linux :: CLI Database Server Settings - Access Control

i would like to change the access control for datebase users via CL: command: /usr/local/psa/bin/database --update-dbuser web1_presta -server localhost:3306 reply: The database user was successfully updated. examination: mysql> select host, user from mysql.user;

+-----------+------------------+
| host | user |
+-----------+------------------+
| % | web1_presta |
| localhost | web1_oxid |
| localhost | web1_presta |
| localhost | web1_shopware |
| localhost | web1_wp |
+-----------+------------------+

Only when using the GUI:
home -> Subscriptions -> Website & Domains -> Databases -> Users -> web1_wp -> Access control
-> from Allow remote connections from any host
-> to Allow local connections only

is also the user adjusted:
mysql> select host, user from mysql.user;
+-----------+------------------+
| host | user |
+-----------+------------------+
| localhost | web1_oxid |
| localhost | web1_presta |
| localhost | web1_shopware |
| localhost | web1_wp |
+-----------+------------------+
