While Portal supports multiple identity stores, is it possible to have one Portal user account that is authenticated by more than one? Sort of a scenario where one identity store is a backup to another, specifically AD and Google. So could a user try and log in with one, and if it is down (or the connection is down) log into the other (either automatically or manually, doesn't matter...), and still be using the same Portal account? Or is it more of a 1:1, where there would be two Portal user accounts, one for one identity store, and one for the other identity store?
Thanks!
