Answer: A
If a password is disclosed when single sign-on is enabled,
there is a risk that unauthorized access to all systems will
be possible. User access rights should remain unchanged by
single sign-on as additional security parameters are not
necessarily implemented. One of the intended benefits of
single sign-on is that security administration would be
simplified and an increased workload is unlikely.
