error using the system D-BUS

[HERC]

Hello all,

I want to register a service on the system bus . I do that as follows

QDBusConnection bus = QDBusConnection::systemBus();
    if(!bus.registerObject("/",obj))
       {
         qDebug() << "error register object";
       }
 
    if(!bus.registerService("org.service")) {
      qDebug() << "error register services ";
      qDebug() << QDBusConnection::systemBus().lastError().message();
    }

QDBusConnection bus = QDBusConnection::systemBus();
    if(!bus.registerObject("/",obj))
       {
         qDebug() << "error register object";
       }

    if(!bus.registerService("org.service")) {
      qDebug() << "error register services ";
      qDebug() << QDBusConnection::systemBus().lastError().message();
    }

If I run my program I get the follow error

"Connection ":1.48" is not allowed to own the service "org..service" due to security policies in the configuration file"

I think I need some configuration in the /etc/dbus-1/system.conf file. Since this is the first time I want to use DBUS, I don't no what I have to put there.

Regards
