To support a new compliance requirement, your company requires positive username attribution of every IP address used by wireless devices. You must collect IP address-to-username mappings as soon as p

UID redistribution is a mechanism to share User-ID mappings between firewalls, not to initially collect them from client devices or wireless infrastructure.

While RADIUS is involved in authentication, relying on the firewall as a direct RADIUS client or proxy for all wireless devices might involve more configuration and potential downtime than simply consuming existing syslog feeds from the wireless controller or RADIUS server.

A syslog listener allows the Palo Alto Networks firewall to parse authentication logs from various wireless devices or their controllers, extracting IP address-to-username mappings without requiring significant configuration changes on the wireless devices themselves.

XFF headers carry the original client IP address in proxy scenarios and do not provide username attribution directly from wireless devices.
