Comment # 3 on bug 1061707 from Wolfgang Bauer

This seems to be a design problem in NetworkManager itself AFAICT, it should
not even ask for the privilege to *modify* the connection (which requires the
root password) IMHO, especially as clicking on Cancel without entering the root
password works as well anyway.

The policy configuration is *not* wrong, changing it to allow all users to
modify shared/system connections would just be a (insecure) workaround.
And according to my knowledge, the security team rejected this anyway.

The same thing happens in GNOME as well btw AFAIK...
At least I remember a bug report about it not too long ago (closed as UPSTREAM
or WONTFIX IIRC, can't find it at the moment though).

Anyway, this is a duplicate of bug#971540.
