<p>I don't fully know this code, but that doesn't sound right.</p>
<p>Your helper is running on the system bus, and shouldn't really have access to the user's session bus at all.<br />
Your client side ioslave will have connections to both busses, but only be talking to the helper on the system bus.</p></div>
</blockquote>
<p>You can set the effective uid of the root process to the users process to connect to user's session bus and then reset it and gain back the privilege.</p>

What you're describing you want is exactly that, except the reply happens a file descriptor. (which as you hint is a native DBus type) Why do you need to register a service in the ioslave?</p></blockquote>
<p>QDBusUnixFileDescriptor object is required to send a file descriptor over dbus. The service must have a method accepting QDBusUnixFileDescriptor as an argument, QtDBus won't create it automatically. KAuth doesn't have any such method thats why the need for a separate service.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R241 KIO</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D6709" rel="noreferrer">https://phabricator.kde.org/D6709</a></div></div><br /><div><strong>To: </strong>chinmoyr, thiago, Frameworks<br /><strong>Cc: </strong>davidedmundson, elvisangelaccio, shortstheory<br /></div>
