I had an application that hooked onto 1 single database.

The app now needs to hook into multiple databases. What we want to do is, using the same application/domain/hostname/virtual dir give the user the option on the login screen to select the "App/Database" they want to connect into.

Each database has the App tables/data/procs/etc as well as the aspnet membership/roles stuff.

When the user enters the username/password and selects (select list) the application, I want to validate the user against the selected applications database.

Presently the database connection string for membership services is saved in the web.config. Is there any way I can override this at login time? Also, I need the "remember me" function to work smoothly as well. How does this work when the user comes back to the app in 5 hours... This process should be able to identify the user and application and log in appropriately.
