How to use openconnect with Cisco Secure Desktop.

Usage

sudo openconnect -v --csd-wrapper=csd-responder-exec.sh --user <user> <https://vpn.mycompany.com>

Alternatively, on OSX you can store your pwd in your keychain and run it like this (place it in a new, 3rd file):

#!/bin/bash

DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

# Get password from OS X Keychain function
get_pwd () {
  security find-generic-password -wa "<name-in-keychain>"
}

echo "**** If you change the password, don't forget to update your password manager and the OS X keychain ****"
echo "**** Retrieving password from keychain ****"
P=$(get_pwd)

# Need to call sudo first because it uses stdin to get the password; it should
# be remembered for the next invocation
sudo echo "Got sudo password..."
cat <(echo "$P") /dev/stdin | sudo openconnect -v \
  --csd-wrapper=$DIR/csd-vpn/csd-responder-exec.sh \
  --authgroup=Employee_Access \
  --user <user> \
  --passwd-on-stdin \
  --servercert sha256:<my-server-cert> \
  <https://vpn.mycompany.com>
