The earliest recollection of this bug is traced back to PAN-OS 9.1.10 - July 29, 2024.
This bug is fixed in PAN-OS versions 9.1.10.
Fixed an issue where the metadata from the firewall's authentication profile was unable to export. This issue occurred when the authentication profile and the SAML Identity Provider sever profile were created with VSYS in the Location and pushed from Panorama template stack values. To utilize this fix, you must upgrade both Panorama and the firewall.
