Yes, it's post auth.  We're all the way into the first couple of
quick-mode steps setting up the SA for ESP when it fails.

I don't see we have any alternatives unless we want to try and implement
heuristics in what to try and that wouldn't make sense.  Seems like it's
a misconfiguration on our end but, for the life of me, I can see what it

There's something broken in the phase 2 transaction I'm not
understanding.  I see vpnc is negotiating a phase 2 of AES w/ 256 and
SHA1 without a problem and that's in our proposition list.  I now have 1
ASA that works with us and 3 that refuse to cooperate with the same
configurations and all 4 work with vpnc.
