 For any reason after rebuilding the container if you are not be able to access MariaDB correctly (i.e. `Access denied for user [...]`) with the previous configuration. Follow these instructions.
 
 First test for network issues. Manually connect to the database through the `backend` container:

 ```
 docker exec -it frappe_docker-backend-1 bash
 mysql -uroot -padmin -hdb
 ```

 Replace `root` with the database root user name, `admin` with the root password, and `db` with the service name specified in the docker-compose `.yml` configuration file. If the connection to the database is successful, then the network configuration is correct and you can proceed to the next step. Otherwise, modify the docker-compose `.yml` configuration file, in the `configurator` service's `environment` section, to use the container names (`frappe_docker-db-1`, `frappe_docker-redis-cache-1`, `frappe_docker-redis-queue-1` or as otherwise shown with `docker ps`) instead of the service names and rebuild the containers.

 The parameter `'db_name'@'%'` must not be duplicated. Verify that it is unique with the command:

 ```
 SELECT User, Host FROM mysql.user;

 Delete duplicated entries, if found, with the following:

 DROP USER 'db_name'@'host';
