18.4. Enable Kerberos authentication

For Kerberos authentication, if the user running the program is already authenticated, for example, if they are using kinit, there is no need to supply a user name or password. If you are using another form of authentication, or are not already authenticated with Kerberos, you can supply these as connection options:

connection.setOption("username", "mick");
connection.setOption("password", "pa$$word");
