The earliest recollection of this bug is traced back to PAN-OS 10.1.0 - May 06, 2026. This bug is fixed in PAN-OS versions 10.1.2. Fixed an issue where, when downgrading from PAN-OS 10.1 to an earlier version, with Cloud Authentication Service configured in an Authentication profile, the firewall did not remove the Cloud Authentication Service from the Authentication profile and displayed the authentication method as None , and subsequent commits failed. If you downgrade from PAN-OS 10.1 to an earlier version and you have configured the Cloud Authentication Service in an Authentication profile, the firewall does not remove the Cloud Authentication Service from the Authentication profile, displays the authentication method as None, and any subsequent commits are not successful. Workaround: Delete the Authentication profile that is configured for the Cloud Authentication Service then commit your changes.
