Fingerprint Logon for Active Directory user on Zorin Core 17.1

I have 17.1 installed on a Lenovo X1C G7 successfully. The fingerprint reader works for a local user. When I logon as a domain (local AD) user, the fingerprint option is missing. I am wondering where the configuration would be to enable this feature. I am new to Zorin but have some experience with various distros over the years. Thanks
