Upon trying to connect you may see: “Connection attempt has failed due to server certificate problem.”
There is no server certificate problem. It’s rather a Cisco client software problem. Let’s fix it for the Cisco QA team.
$ sudo apt-get install ia32-libs lib32nss-mdns
Make this directory. You don’t need firefox – only need to make this directory which the Cisco software queries for some odd reason.
$ sudo mkdir /usr/local/firefox
Link to the 32bit certificates you have installed from apt-get:
$ sudo ln -s /usr/lib32/libnss3.so libplc4.so libnspr4.so libsmime3.so /usr/local/firefox/
$ sudo ln -s /usr/lib32/nss/libsoftokn3.so /usr/local/firefox/
Now it works!
