Error with basic authentication - Reporting Service Add In for Sharepoint

Maybe someone can help me. I am running the reporting service add in for Sharepoint and we have only Basic Authentication running on our site (it is on SSL). When i try and open a report in sharepoint it errors out on me. When i go back into IIS and set Windows and Basic authentication it works, but it requires me to enter our domain and username. We need to only use Basic so it will not need the domain. Anyone have any suggestions on what i can do to make this work?i'm having this issue, too. help?
