SAML authentication fails after upgrading to PAN-OS 10.1 in a mutli-vsys environment

• Panorama Managed Firewall or Standalone Firewall.
• PAN-OS 10.1 and above.
• SAML authentication profile pushed from Panorama and is in a shared location or local SAML authentication profile in a shared location.
• GlobalProtect authentication.
• Authentication Portal.

• The authentication fails as it is referring to vsys1 whereas the SAML authentication profile is in a shared location when pushed from Panorama
• For example, below is the username and SAML authentication profile used in the configuration:
  • User: user1@testlab.com
  • SAML Authentication Profile: SAML-Auth-Profile
• In the authd.log below, the SAML authentication profile SAML-Auth-Profile is referring to vsys1 but the profile is in the shared location

> tail follow yes mp-log authd.log

debug: pan_auth_cache_user_is_allowed(pan_auth_cache_allowlist_n_grp.c:786): user "user1@testlab.com" is NOT 
in allow list of auth prof/vsys "SAML-Auth-Profile/shared" (vsys in request "vsys1")

• Same is observed if the SAML authentication profile SAML-Auth-Profile is configured locally on the firewall

1. The issue is fixed in PAN-190454 and available in PAN-OS 10.2.4, 10.1.9, 11.0.1
2. Upgrade to the fixed version resolves the issue.

Workaround: Change the location of the SAML authentication profile from shared to a specific target vsys where it is invoked
