Unable to connect using openconnect in Ubuntu12.04

[Sharad Upadhyaya]

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

Any help would be appreciated.
