How can I change the username that is used to connect to a SharePoint site in Microsoft Document Connection. When I try to connect to a site, it's showing the authentication screen, but only allows me to enter the password. The username is defaulted to my Mac login user, but I can't change it (it's greyed out). Connecting using these credentials does not work, it always displays "You do not have permission to connect".
For a successful connection, I think I have to prefix my username with the name of our Windows domain, e.g. DOMAIN\username. Unfortunately, Microsoft Document Connection does not allow me to do that.
Any ideas on how I can change the username?
