Welcome greg_g3 to Centrify Community!
The smart card should appear in the Keychain with its certificates displayed. If the smart card does NOT appear in the Keychain, then please make sure the firmware of the smart card reader itself has been updated to the latest version (See the following page for more information: https://militarycac.com/macnotes.htm#see_the_reader)
I would also like to refer a nifty troubleshooting document available on Centrify knowledge base for further assistance, https://centrify.force.com/support/Article/KB-3018-Troubleshooting-smart-card-issues-on-Mac-systems
