--- Comment #34 from Luca Beltrame firstname.lastname@example.org 2014-07-16 09:13:02 UTC --- In KAuth, the action autentication is IIRC done by the helper KAuth is calling, not KAuth itself.
For a breakdown of how KAuth works, which may lead to an understanding of the issue:
As I said, KAuth is community-maintaned (no single maintainer). That's why I mentioned kde-frameworks-devel. Contacting individual developers is likely to be inefficient on this regard.
