The user cecacons has been granted access to remotely connect to the database cecacons_elektroschirmer from any IP.
Yes.
Yes.
In the past we granted open access to all databases from all users from all IPs, but that is a rather insecure way to do things. We're now doing something more along the lines of https://johnny.heliohost.org:2083/frontend/paper_lantern/sql/managehost.html where you can grant access much more securely. Until we write a custom Heliohost only plugin for doing this yourself you'll just have to make requests for it.
