Description:
i am trying to set up a vpn connection through gnome network manager applet using openconnect and .p12 certificate, i am able to connect to vpn gateway, and enter certificate credentials (pin code), but after entering user credentials i got scarce error message about connection failure, so i have attached part of the log below.

Steps to reproduce:
Actually it's hard to provide real steps to reproduce, because i don't know how the VPN gateway is configured to receive this kind of certificates, in case additional log or configuration information will be needed, please comment and i will provide necessary information.
