Login to Webmin with AD account

Hello,
How do I authenticate AD users in webmin? I followed below steps from various posts but no success…

I have a RHEL 8 server configured to join domain using realm join
I can SSH to the server with domain account.

To enable webmin for AD auth , I found this post Reddit - Dive into anything

I updated /etc/sssd/sssd.conf under the [domain/ad.mydomain.local] section:
access_provider = ad
ad_gpo_access_control = enforcing
enumerate = true

visudo
%Domain\ Admins ALL=(ALL:ALL) ALL

Restarted SSSD service after all edits.

I also updated webmin->Authentication module with Full PAM Conversations, Pass on PAM status to other modules.

What errors appear in the relevant logs?

When I login with user@domain format on webmin, I see a generic error in Webmin Actions Log - “Login to webmin failed: Invalid password”
Is there another log with finer details I can look?
