Thanks for the response! Chrome OS provides crosh, which is a very stripped down command line utility, so I cannot run openconnect --version, however on the about tab, it says OpenConnect for Android Version 1.11. Chrome OS offers two "middleware" apps designed to allow 3rd party apps to access the CAC: CACKey and CSSI Smart Card Middleware. I would assume it is these apps that provide the p11-kit module file for apps needing to authenticate with the CAC. However, I do not know how to get these Chrome OS Web Store apps to talk to the Play Store OpenConnect, nor do I know how to diagnose the location of the p11-kit module from these apps. I am pursuing other leads to get answers to these questions as well, but so far no luck. Worst case scenario I would have to install Crouton and Linux on my Chromebook, but I would like to avoid this and keep the OS verification security.
