I need a Authentication / Group Membership system set-up within my VB Silverlight 4 application. This system should allow for multiple businesses to set-up a Company Group that holds company members with different Administrative privileges. Also, all data entered can only be viewed by the company that entered the data(queried by maybe a unique CompanyID. All tables must be viewable by the creating company. Admin page needs to be contructed with a datagrid that shows a LIST of Company users. The company admin person can also add and edit users from this area. I will be the only SuperAdmin. This is a private project for Solutronix. You bid $150.
