Explanation

The administrative accounts are defined on an external SAML, TACACS+, or RADIUS server. The server performs both authentication and authorization. For authorization, you define Vendor- Specific Attributes (VSAs) on the TACACS+ or RADIUS server, or SAML attributes on the SAML server. PAN-OS maps the attributes to administrator roles, access domains, user groups, and virtual systems that you define on the firewall. https://docs.paloaltonetworks.com/pan-os/9-1/pan-os-admin/firewall-administration/manage- firewall-administrators/administrative-authentication
