Finally some useful information. I know I been slow about this, but now its here okay? good, now let’s get moving.
Actually I’m not gonna set up a complete tutorial on this issue; someone else did just that. And yes, it works. Just wanted to keep the site alive, so I decided to mirror it.
The original guide (and files) are located over at http://wiki.cacert.org/wiki/eToken, with references to the real guide (and files) at http://njumaen.dyndns.org/files/eToken/mozilla.html. Its just a matter of installing the driver, and the utilities, and voila! It works perfectly under Vista – no driver issues or nothing.
I know this sounds like a Works For Me(tm) solution, but hey..official Vista-compability is not really something you see everyday (yet).
Have fun authenticating yourselves!
