Comment # 3 on bug 1201123 from Jonathan Kang

In openSUSE, we use a relatively strict policy for
org.freedesktop.NetworkManager.settings.modify.system. So when programs/users
modify or update a system wide connection, an authentication is required. For
example, this happens when you edit and save a connection via
gnome-control-center.

The reason why steam requires this is not clear. Since steam is not open
sourced, there is nothing we can do to fix this.

To work around this, you can modify
/etc/polkit-1/rules.d/90-default-privs.rules.

Change
> 'org.freedesktop.NetworkManager.settings.modify.system':
>     [ 'auth_admin_keep', 'auth_admin_keep', 'auth_admin_keep' ],

to

> 'org.freedesktop.NetworkManager.settings.modify.system':
>     [ 'auth_admin_keep', 'yes', 'yes' ],
