nextcloud with database server on different host

Hi all, I'm asking me (and you) if it's intended to setup nextcloud with defined owncloud__database_server: some-server not on localhost without creating user/password/db on this host by my own. My idea was that the task to create database and users ist delegatet to the database server. But while setting up nextcloud on TASK [owncloud : Automatically finish setup via the occ tool] *********************************************************************** I get an error on "Failed to connect to the database: An exception occurred in the driver: SQLSTATE[HY000] [1698] Access denied for user" which is logical since there is no user and database created. Any ideas? Thanks and regards. Jan
