Comment # 4 on bug 971540 from Wolfgang Bauer

A further note:
You can of course also change the polkit rules on your system (as suggested in
the KDE bug report) to get rid of that root password request.
Add the following line to /etc/polkit-default-privs.local, and run
/sbin/set_polkit_default_privs to apply the change:
org.freedesktop.NetworkManager.settings.modify.system yes

We (the openSUSE KDE team) cannot randomly change the distribution-wide polkit
defaults to our needs/preference though. This would have to be decided by the
security team.
And it of course would affect the whole distribution, not only KDE.

Anyway, as the KDE bug report is open again, I'm going to close this as
UPSTREAM for now.
Let's see what happens there...
