XML response has no "auth" node

[Will Crisp]

I'm getting the subject error message, "XML response has no "auth"
node", when attempting to connect to my work's VPN concentrator.  What
follows is output of my connection attempt.  I can establish SSL
connection, but I can't get further than that.  I will attempt to
connect using Windows (later today hopefully) and compare results, but
hoping someone on this list has some ideas what else I can try to
connect from Linux.

Thanks,
-Will
