[CentOS] CentOS 6.7->6.8, ssh-add issue

Folks,

I am perplexed. I updated my workstation at work Wed before I left, from 6.7 to 6.8. Then, yesterday, I went to use ssh-add -s libcoolkeypk11.so, which I've done many times before to add the certs from my PIV card... and 100% of the time if fails, letting me SSH_AGENT_FAILURE, cannot add card.

Now, using a script called sccr, which uses my public and private key to generate a one-time password (we use the to sudo to root), works with no problem. I used my card to go into the data center this morning, which also reads my card, and had no problem. I've tried eval $(ssh-agent) to start a new instance. Nothing works.

Also, pklogin-finder finds the cards, asks for my PIN< and it works.

Clues for the poor?
