That's the right thing to do for now.  Auth information is sent to the
plugin initially and auth is one-shot; if the given credentials fail,
the user needs to change them and try again.  Clearly suboptimal but
what we're stuck with for now.

I rewrote most of the VPN stuff a week ago to support multiple active
connections and interactive authentication but it was simply
irresponsible to commit that patch so close to a 0.7 release.  I've
still got the patch and we can land it after 0.7 comes out, as long as
we make it clear we aren't guaranteeing the VPN plugin D-Bus interface
and libnm-glib API in 0.7.

Or I'm tempted to drive towards a 0.8 release with these features (modem
manager, bluetooth, better vpn).  Not sure yet.
