I'm moving to LDAP auth with Duo 2FA. We need a better answer than RADIUS as we've found Duo's Authentication Proxy functionally limited and crash-prone. Using Mitch Densley's video guide for PAN-OS 8.x as a starting point, I've gotten my Duo application set up, along with an authentication profile. However, when I try to create an Authentication Enforcement object, my Duoized authentication profile doesn't appear on the menu (only "None"). If I skip that step momentarily and try to create an authentication policy, I can't select the zone my captive portal interface is in. Can't tell what I'm missing or how my environment differs from the how-to-- I'm using PAN-OS 9.0.4 in an HA cluster managed by Panorama.
