Authorities required to create a connection by JT400 without supplying username/password

Question

What authorities are required to create a connection by AS400JDBCDriver.connect() without supplying username/password.

Trying to create a JDBC connection by using jt400 APIs without supplying the username/password as:

AS400 system = new AS400();
AS400JDBCDriver driver = new AS400JDBCDriver();

Properties prop = new Properties();
prop.setProperty("translate binary", "true");
prop.setProperty("prompt", "false");
prop.setProperty("naming", "sql");

String schema = "MySchema";
connection = driver.connect(system, prop, xref);

Details: If running on IBM i, the target is the local system. This has the same effect as using localhost for the system name, *CURRENT for the user ID, and *CURRENT for the password.

com.ibm.as400.access.AS400

I am getting the exception:

java.sql.SQLException: The application server rejected the connection. (User ID is disabled

So my question is:

What authorities are required to create a connection by AS400JDBCDriver.connect() without supplying username/password??
