I was missing the XML policy file. After creating one, it worked flawlessly. Thank you very much Daniel,
One more question, I have been looking at systemd public man pages[0] as the sd-bus API reference, but I can't find documentation about some functions. For example information regarding vtable handling (sd_bus_add_object_vtable for and it's sd_bus_table fields...) In this case, I have found some information after looking to examples[1] and to the source code[2], but I'm missing some bits (flags meanings). Is there any more information anywhere ?
