Explanation:

The unifyingUserDataProvider can be used to merge two or more other user data providers into one.

The unifyingUserDataProvider will forward a login attempt (username and password) to each inner user data provider in the order they are specified. After one of the inner user data providers returned a successful login (and returned the user's attributes), the procedure terminates. If no inner user data provider could verify the user, the login attempt fails.
