Hi,everyone
I encountered a problem when send dbus method call message.Program A which runs as root user provides system-wide dbus service interfaces.When another program B with root permission send method call message to A,It received the error info:
Error org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 1 matched rules; type="method_call", sender=":1.41" (uid=0 pid=3397 comm="dbus-send --system --print-reply --type=method_cal") ...

But when I run prgram B in generic user permission,localmachine for example,it success to send message.It confused me all the day.Is there anyone also encountered this issue? Any clue is appreciated.

I have yet solved this issue.Just modified the configure file under /etc/dbus-1/system.d
add the following lines in ***.conf
<policy context="default">
<allow send_interface="the interface to be exported"/>
...
</policy>

Thank you very much for the follow up to your own post. I was having a similar problem, and then saw your solution. You probably saved me several days of work. Many thanks!
