802.1x Authentication

All,


Just looking for some more information on wired 802.1x authentication.  I currently run ACS 4.1, and I know that it can be integrated with AD for authentication purposes.  Does anyone have information on whether or not you can take it a step further & use CAC / smartcard authentication?  There's not much information that I can find about this topic, so anything posted is helpful!

Thanks -

Jon

The ACS supports RSA among other things. What solution are you running?

We're currently using CAC authentication (Common Access Cards).  I did see that RSA is supported, but we don't use

RSA tokens right now.

Thanks

With the CAC cards, don't you end up pointing to an LDAP to verify the certificate?  I would assume that all you'd need to do is make sure you have the

root and subordinate certs trusted in ACS then point to an LDAP as the external directory (instead of AD) where you can verify the certs.

HOWEVER, my experience with 802.1x and ACS (limited as it may be) has been that you still need a supplicant on the client side to handle the certificate auth communication.
