Hi, I am trying to connect to a CISCO SSL VPN using OpenConnect v3.15 on Ubuntu 12.04.5 LTS (headless). It fails just after I enter my userId and pw - with the comment 'SSL certificate authentication failed'. The complete output is as follows: user-01:~$ sudo openconnect serverIP:443 Attempting to connect to serverIP SSL negotiation with serverIP Server certificate verify failed: self signed certificate Certificate from VPN server "serverIP" failed verification. Reason: self signed certificate Enter 'yes' to accept, 'no' to abort; anything else to view: yes Connected to HTTPS on serverIP GET https://serverIP/ Got HTTP response: HTTP/1.0 302 Object Moved SSL negotiation with serverIP Server certificate verify failed: self signed certificate Connected to HTTPS on serverIP GET https://serverIP/+webvpn+/index.html SSL certificate authentication failed Please enter your username and password.
