    Description

      After upgrading Maxscale from v2.5.18 to v6.2.1, I can see in maxscale.log this warnings:

      2022-02-02 09:54:42   warning: (65) [MariaDBProtocol] (WritableService); COM_CHANGE_USER from 'user' to 'user' succeeded on MaxScale yet failed on backends.

      We are primarily using PHP with the PDO_MYSQL driver to connect to the database. Users are generally configured statically and not changed on the fly.
      > Also, what connector you are using to connect with maxscale ?
      MariaDB-client-10.5.12_8-1.el8.x86_64
