Question:
JAAS Single Sign-on. Suppose you have following authentication services: NT domain, some implementations of SmartCard and Kerberos, and your own SampleLoginModule. You need to implement following authentication strategy: 1. User should be authentication in SampleLoginModule. 2. Users should be authentication via SmartCard but NT authentication can substitute SmartCard. 3. NT authentication is enough to login to the system. 4. Kerberos-authentication users are granted additional permissions. What JAAS login configuration does implement the policy described above?


Login {

       sample.SampleLoginModule required;

       com.sun.security.auth.module.NTLoginModule sufficient;

       com.foo.SmartCard requisite;

       com.foo.Kerberos optional;

    }


Login {

       sample.SampleLoginModule optional;

       com.sun.security.auth.module.NTLoginModule required;

       com.foo.SmartCard requisite;

       com.foo.Kerberos sufficient;

    }


Login {

       sample.SampleLoginModule optional;

       com.sun.security.auth.module.NTLoginModule sufficient;

       com.foo.SmartCard requisite;

       com.foo.Kerberos required;

    }


Login {

       sample.SampleLoginModule sufficient;

       com.sun.security.auth.module.NTLoginModule required;

       com.foo.SmartCard requisite;

       com.foo.Kerberos optional;

    }


Login {

       sample.SampleLoginModule sufficient;

       com.sun.security.auth.module.NTLoginModule requisite;

       com.foo.SmartCard requisite;

       com.foo.Kerberos required;

    }
