Importing user passwords from Drupal 5

Sure thing. Here's my code, in its entirety:

class D5UserMigration extends UsersExampleMigration {
  public function __construct() {
    parent::__construct();
    $this->description = t('Users from old D5 site');
    $this->map = new MigrateSQLMap($this->machineName,
        array('uid' => array(
                'type' => 'int',
                'not null' => TRUE,
                'description' => 'User ID.'
                )
             ),
        MigrateDestinationUser::getKeySchema()
    );
    $query = db_select('usersd5', 'udf')
             ->fields('udf', array('uid', 'name', 'pass','mail','created','access','login','status','language','init'));
    $this->source = new MigrateSourceSQL($query);
    $this->destination = new MigrateDestinationUser(array('md5_passwords' => TRUE));

    $this->addSimpleMappings(array('status', 'mail','created','access','language', 'login','init'));
    $this->addFieldMapping('name', 'name');

    $this->addFieldMapping('pass', 'pass');

    $this->addFieldMapping('roles')
         ->defaultValue(2);

    $this->addUnmigratedDestinations(array('theme', 'signature','timezone', 'picture','signature_format','field_migrate_example_gender','path'));

  }
}

Changed status since the requested field mapping was posted.
