RADIUS

Remote Authentication Dial-In User Service (RADIUS) is a broadly supported networking protocol that provides centralized authentication and authorization. You can configure RADIUS authentication for end users or administrators on the firewall and for administrators on Panorama. Optionally, you can use RADIUS Vendor-Specific Attributes (VSAs) to manage administrator authorization. RADIUS VSAs enable you to quickly change the roles, access domains, and user groups of administrators through your directory service instead of reconfiguring settings on the firewall and Panorama. You can also configure the firewall to use a RADIUS server for:

When sending authentication requests to a RADIUS server, the firewall and Panorama use the authentication profile name as the network access server (NAS) identifier, even if the profile is assigned to an authentication sequence for the service (such as administrative access to the web interface) that initiates the authentication process.

The firewall and Panorama support the following RADIUS VSAs. To define VSAs on a RADIUS server, you must specify the vendor code (25461 for Palo Alto Networks firewalls or Panorama) and the VSA name and number. Some VSAs also require a value. Refer to your RADIUS server documentation for the steps to define these VSAs.

Alternatively, you can download the Palo Alto Networks RADIUS dictionary, which defines the authentication attributes that the Palo Alto Networks firewall and a RADIUS server use to communicate with each other, and install it on your RADIUS server to map the attributes to the RADIUS binary data.
