im in the is it possible phase with a product.  basically my design would be one UI for up to 100 structurally identical databases.  the way i have it in my head right now, is a user would log in, that login would go to a central authentication server and authenticate the user.  the response from that server would include the database that the user is supposed to access.  one user would never be allowed to access more than one database.  but what i need to know is using seam and hibernate, is it possible to have an authentication start, that authentication then tell seam which database connection to use with that user for that session?

anyone got an example or tutorial for something like this?
