1. Run sudo micro /etc/pam.d/sudo
2. Add auth sufficient pam_tid.so below auth sufficient pam_smartcard.so, so that the file looks like this:

# sudo: auth account password session
auth        sufficient      pam_smartcard.so
auth        sufficient      pam_tid.so
auth        required        pam_opendirectory.so
account     required        pam_permit.so
password    required        pam_deny.so
session     required        pam_permit.so
