nm-applet authentication works only in gdm+gnome/unity session

Authentication for creating/editing system connections in nm-connection-editor works only in gnome/unity session started via gdm.
Other combinations result in "available to all users" checkbox being grayed out or "insufficient privileges" error.

Tested cases:
 - gdm + openbox session.
 - no dm + "ck-launch-session dbus-launch openbox-session" + workaround of broken ck session management in bug #483130

in both tested cases nm-applet fails to authenticate user to edit/create system connection.

console output when trying to create system wireless connection: insufficient privileges when hitting "save" button
