cisco secure desktop

[ChadDavis]

I'm trying to connect to my companies vpn with open connect.  I'm
running Debian linux.  I'm having trouble, obviously ;)  So, normally
my company has users install the cisco vpn client via an applet that
automagically sets everything up for you.  This applet hangs
indefinitely in my browsers.  I can't quite sort out yet what the
problem is.

However, I found openconnect in the debian repos and went with it.
Wonderful integration with the network manager; impressive improvement
over recent years.  However, when I actually try to connect to the
vpn, it complains about a lack of Cisco Secure Desktop.

I need troubleshooting advice.

Here's the actual error.  See below for MORE INFO.

Then if I hit the "connect" icon again while this is happening . . .

It then asks for credentials, accepts them ( why didn't it ask for
credentials the first time? ), and then it craps out, reporting this
error message:

"Unable to complete connection: Cisco Secure Desktop not installed on
the client."
