Cisco IPSec with certificate

Hi, all.

I'm one that, among many, I've lost the Cisco VPN client because of the 64-bit kernel.

I searched the Cisco groups and this group without any result. That is any result trying to use OS X VPN with certificates!

Other had better luck because they have the couple username/password (or shared secret).

The Cisco client only need my certificate and the one that the CA issued (my organization, BTW).

I wasn't able to insert these certificates, though both of them are in the keychain, the ones I inserted in the Cisco client from, years ago.

OSX VPN in Cisco mode wants a machine certificate, instead. Certificate that doesn't seem to be anywhere in the keychain.

So..

How can I use OS X VPN to log into my organization's net?

Or else, is there a workaround (not involving Cisco to-be-purchased software)?

Thanks,
