Re: Problem to add a broadband connection on NetworkManagerUserSettings

[Maxwell Chiareli Xandeco <maxwell xandeco br flextronics com>]

I'm using Ubuntu 9.10, with your code I don't get errors but a connection is not added, nothing happens when I call AddConnection method.

Follow my policy file:

<!DOCTYPE busconfig PUBLIC

     config file assumes that D-Bus will deny rules by default unless
     explicitly over-ridden with an <allow /> tag.
