XBAP Security


We have a small XBAP file upload app that we are having trouble deploying. We were getting security errors when we were pushing this application that we don't get when running in our development environments on our machines. We gave the XBAP app full permissions and still got errors. Then we created a personal certificate and were able to get this to work. But that means we have to load a client side certificate for each and every machine that wants to run this which is ridiculous. Does anyone have a solution for this?
