ASP.net roles and Projects
For our extranet web application we are implementing Forms authentication.  

In our system an Account (Company) has 1 or more Projects. We don't want to create new user logins for all of the Projects. But a user has a specific role for the account and a role per Project.

 - When the user is the primary contact of the active project, he is allowed to change the Company's CRM data.

 - When the user is the primary contact of the active project, he is allowd to see all the navigation items within the portal.

 - However when a new project is exported to the extranet, he might no longer be primary contact. And lose this role for the Account and new project. However still has this role for the first project.

Any clue how to combine this with the asp_net tables in a nice way?
