Works for example with the following polkit rule.

# cat /etc/polkit-1/rules.d/50-mageia-wheel.rules
/* Allow members of the wheel group to execute the defined actions 
 * without password authentication, similar to "sudo NOPASSWD:"
 */
polkit.addRule(function(action, subject) {
    if ((action.id == "org.mageia.drakconf.pkexec.run" ) &&
        subject.isInGroup("wheel"))
    {
        return polkit.Result.YES;
    }
});
