You may get an error that says "Secure Client cannot confirm it is connected to your secure gateway" when you try to connect to the VPN in Step #4. This happens because the Cisco Secure Client maintains its own list of certificates to authenticate remote servers - it does not use the system's certificates. The Cisco Secure Client certificate database is in /opt/.cisco/certicates/ca
It is likely that your installation of Linux has the right certificates already because they are frequently included with web browsers and other tools.
To remediate, copy the USERTrust certificates by doing:
| sudo cp /etc/ssl/certs/USERTrust_* /opt/.cisco/certificates/ca/ |
Retry Step #4
