Hello, I have been working on this problem for a few days now and have exhausted my testing knowledge for this problem. I currently have a fresh install of Xubuntu 14.10 32-bit on a Dell inspirion 6000. I am trying to use openconnect to a Cisco VPN server by logging in with a CAC. I have followed the steps at the link below to enable CAC login. http://www.gooze.eu/fr/forums/support/howto-connect-to-cisco-anyconnect-vpn-using-openconnect-and-pki-token Xubuntu 14.10 installs the following packages from the repository. openconnect 6.00-1 gnutis-bin 3.2.16 From here I run the command openconnect -c 'pkcs11:model=PKCS%2315%20emulated;manufacturer=piv_II;serial=06b508843810d7f6;token=PIV_II%20%28PIV%20Card%20Holder%20pin%29;id=%01;object=PIV%20AUTH%20key' vpn.server.srv And this is my output: POST https://vpn.server.srv/ Attempting to connect to server XXX.XXX.XXX.XXX:443 PIN required for PIV_II (PIV Card Holder pin) Enter PIN: Error loading certificate from PKCS#11: The requested data were not available. Loading certificate failed. Aborting. Failed to open HTTPS connection to vpn-outside.nrlssc.navy.mil Failed to obtain WebVPN cookie I have not been able to get any additional error details. Even when setting the verbose option the output is still the same. Is it possible to point me in the right direction to fix this issue. Thank you,
