CAC modules

[Mcclelland, Michael B Mr CTR USN USA]

Hopefully I'm not stepping out of bounds of the intended subject matter for
this list.

I am using Ubuntu 12.04 and I need to authenticate to a cisco asa which
requires DOD CAC certificates.  Is it possible to use a CAC module with
OpenConnect such as the libcoolkeypk11.so or libcackey.so as I do with
firefox?  

Thanks in advance for your advice.
