What were you trying to do that didn't work?

I was trying to configure sssd to work with smart cards. The new way of specifying shadowutils works, however, it seems it's not backward compatible and we can not log in with "id_provider = files" anymore.

How reproducible:

Always

Please provide the package NVR for which bug is seen:

sssd-2.9.3-2.el8.x86_64

Steps to reproduce

I used the config. In there, there is the old configuration of sssd which doesn't seem to work:
[sssd]

debug_level = 9

services = nss, pam, ssh, sudo

domains = shadowutils

certificate_verification = no_ocsp

[nss]

debug_level = 9

[pam]

debug_level = 9

pam_cert_auth = True

[domain/shadowutils]

id_provider = files{}

Expected results

Smart card login should succeed. Su command and GUI should prompt for smart card pin and login if the pin is correct.

Actual results

Su command is asking for user password and GUI is prompting "Please (re)insert (different) Smartcard".
