I am having a bit of trouble with some two factor authentication setup.
My endgoal is to use our certifications on our CACs to serve as our two factor authentication for our network.
Most ideally, without having to buy anything, as purchasing anything in the government is near to impossible.
We are running TACACS+ 5.5.0.46 on a Linux box, and I am testing this config on a 3750X running 15.2(4)E1.
I used this guide:

I was able to follow along up until it came to the ssh software, like I said, can't purchase anything right now. I did manage to get ahold of a version of putty that can pull certs from the card, retrieved here:

I keep getting an error that says:
"Disconnected: No supported authentication methods available (server sent: publickey)"
Has anyone done this, or have any ideas?
