Problems connecting to VPN that insists on downloading secure desktop

[Martin Uhrin]

Dear Openconnect community,

I'm trying to connect to our Uni VPN which I haven't done with
openconnect before so I have no idea if I can expect it to work.

The latest failure I get is 'Failed to exec CSD script
/tmp/csdq9y1Q8'.  I realise that I can supply a custom script but what
would this have to contain?

Would someone be able to see if they can get past this stage of
communicating with our server?

Many thanks,
-Martin
