+On Debian, you need to manually create a database and a database user prior to starting the web wizard.
+This is due to local security restrictions whereas the web wizard cannot create a database/user through
+a local unix domain socket.
+
+```
+MariaDB [mysql]> CREATE DATABASE icingaweb2;
+
+MariaDB [mysql]> GRANT ALL ON icingaweb2.* TO icingaweb2@localhost IDENTIFIED BY 'CHANGEME';
+```
+
+You may also create a separate administrative account with all privileges instead.
+
+> Note: This is only required if you are using a local database as authentication type.

 `/icingaweb2/setup`.
