{@inheritDoc}

<p>This implementation simply returns the provided
{@code authenticatedUser} without modification. Implementations that
wish to update a user's {@link AuthenticatedUser} object with respect to
new {@link Credentials} received in requests which follow the initial,
successful authentication attempt should override this function.
