How to auto save a Cisco VPN connection password on Mac OS X?

There is a workaround with AppleScript that works for me.

In the bad old days of using Cisco's client, it was easy to edit the .pcf file to work around the remote server policy. Using the alternative client Shimo has worked for me as of a couple of years ago (it's now closed-source, but you can get the old version from Google Code). Here's another workaround I haven't tried that uses the Keychain.

I got another script on github.

Instead of simulating click and input, this script access the process and simply triggers the actions.

While the first time the script runs, OSX may ask for accessibility.
