In most cases it's self limiting; the user only knows one set of credentials. Alternatively, there may be a couple different credentials that map to a single principal. We have such a use case here at Virginia Tech, where users may authenticate via either username/password or X.509 certificate. In either case, however, it's the same principal after authentication. If you have a case where you have multiple authentication backends, where one user may have a different security principle in each authentication source, you're in a situation that CAS is ill-equipped to handle.
