Since my upgrade on 11.10-beta1, I cannot edit my VPN-settings anymore. Under nm-applet => VPN the edit-button is greyed out. Unter the settings => network => vpn => configure, I get the error message "insufficient privileges".
My account is member of the admin-group, which should be allowed to change the settings:
# id lars
uid=1000(lars) gid=1000(lars) Gruppen=[...],119(admin),[...]

Identity=unix-group:admin
Action=org.freedesktop.NetworkManager.settings.modify.system

Are there any privileges, that are checked beside the ones in PolicyKit?
