kinit failing when AD user joining using smaercard PIN on ubuntu 20.04

[Pal, Vikram]

Hello,

We are login to Ubuntu 20.04 device using smartcard PIN. We are able to login as AD user successfully.
We are using Windows 2019 AD Server.

But when we run command klist, klist is empty.

We tried kinit manually but it's throwing error. It asks for PIN but immediately asks for password without waiting for pin to be entered.

PFA the screenshot.

Regards,
Vikram
