One of my clients has an inhouse application that connects to multiple MySQL databases with the same user credentials. I really don't know a ton about this application, other than it would be quiet difficult to rewrite. My question - how do / (can) I set up multiple databases for this client, yet allow each database to use the same username? When I've tried creating two databases (difference DB names, obviously) with the same username I get the following error "There is already a database user with this name on the server. To get a unique name, e.g. prepend your domain name to the username." Thanks.
