Hi
Welcome to Centrify community!
After some resaerch online, I noticed that native MacOS smartcard does support Kerberos authentication as mentioned below:

Meanwhile, I will try to reproduce the issue on Chrome and see if that is an expected behavior. Can you also test with other browser and see if you experience the same problem?
Please keep us posted. Thank you!
