I have look through a few answers on SO for a solution to this. I have tried everything on the question page HERE but to no avail. Once I change the user to something else, it will work and show the page, but my web-app is unable to make a connection to the database as any other user is unauthorised to access the DB in my dev-environment.
I have tried copying the settings from another person on the dev-team who it works for but it still doesn't work.
