Comment 10 for bug 954747

As far as I know this should work. A very similar configuration on my Cisco 881 (admittedly, it's not an ASA) works just fine like this and properly adds the extra domain. Is vpnc also at the right version, which should be 0.5.3r512-2ubuntu1?

If it is, I'd like to suggest you file a separate bug for your issue, and make sure to notify me with the bug number here or by email -- then we'll debug the network-manager-vpnc plugin directly to figure out what is going wrong.
