Cannot authenticate on Apache Cassandra 2.2.x

Question

Trying to accomplish a simple proof of concept using Spring Data Gosling (RELEASE) and Spring Data Cassandra (1.3.0.RELEASE, imported from the parent BOM). The configuration class I use is the following:

@Configuration
@PropertySource(value = { "classpath:/cassandra/cassandra.properties" })
@EnableCassandraRepositories(basePackages = { "com.test.repositories" })
public class CassandraConfiguration extends AbstractCassandraConfiguration {

    @Autowired
    private Environment environment;

    @Bean
    @Override
    public CassandraClusterFactoryBean cluster() {
        CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean(); 
        cluster.setUsername(environment.getProperty("cassandra.username"));
        cluster.setPassword(environment.getProperty("cassandra.password"));
        cluster.setContactPoints(environment.getProperty("cassandra.contactpoints"));
        cluster.setPort(Integer.parseInt(environment.getProperty("cassandra.port")));
        return cluster;
    }

    @Override
    protected String getKeyspaceName() {
        return environment.getProperty("cassandra.keyspace");
    }

    @Bean
    @Override
    public CassandraMappingContext cassandraMapping() throws ClassNotFoundException {
        return new BasicCassandraMappingContext();
    }

}

Starting the program leads to an error regarding authentication:

Using AllowAllAuthentication on the Cassandra side works flawlessly. The problem appears when I use PasswordAuthentication. On Cassandra 2.2.x, dependency analysis shows the whole package is depending on the Datastax cassandra-driver-dse version 2.1.8 (which, on the other side, depends on the cassandra-driver-core 2.1.8). Forcing the driver dependency to the actual 2.2.0-rc3 leads to other problems, probably because it's still in an unsupported state.

Should I give up using data-cassandra with C* 2.2? Thanks.

Turns out spring-data-cassandra 1.3.0.RELEASE CAN authenticate towards Apache Cassandra 2.2.x All you need is building an AuthProvider object. The DataStax driver provides a concrete implementation for this interface: PlainTextAuthProvider. The final cluster() method should be created like this:

@Bean
@Override
public CassandraClusterFactoryBean cluster() {
    CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean(); 
    PlainTextAuthProvider sap = new PlainTextAuthProvider(env.getProperty("cassandra.username"), env.getProperty("cassandra.password"));
    cluster.setContactPoints(env.getProperty("cassandra.contactpoints"));
    cluster.setPort(Integer.parseInt(env.getProperty("cassandra.port")));
    cluster.setAuthProvider(sap);
    return cluster;
}
