I'm using freeradius as the radius server and trying to connect it with a PA-500. (I tried to access the freeradius setup document at https://live.paloaltonetworks.com/docs/DOC-1238 but I am apparently unauthorized - do you know what level of support you need to access it?)
When I try to access a website that requires captive portal, the authentication page appears but I am unable to authenticate my username/password. The radius server is also not seeing the authentication request, so I suspect this is a network connectivity issue.
The radius server is located in a zone that has access to the "outside" web server and the "inside" host has access to the radius server "zone".
All of my ports are configured to be Layer 3.
I'm having a lot of difficulty because I'm lacking visibility on exactly what is happening... is there a way to verify that my radius server is indeed communicating with the PA-500?
The PA-500 has been upgraded to PAN-OS 3.1.6 .
I don't see the captive_portal.log anymore under #tail mp-log
I get the following errors in authd.log (does that cover both captive portal and admin?):
admin@PA-500> tail mp-log authd.log

The above log does not look like captive portal problems. On the GUI, under Monitor > System, I see two related error messages:
|01/11 16:06:34||general||informational||general||Captive portal authentication failed for user: pek on 10.1.0.2, vsys1|
|01/11 16:06:32||general||informational||auth-fail||User 'pek' failed authentication. Reason: Invalid username/password From: 10.1.0.2.|
I've simplified my network configuration to be a star network (essentially flat where the the Palo Alto is in the middle doing routing between devices) and all active interfaces are in one zone.
I'm still stuck trying to figure out why the radius server is not receiving authentication requests from the palo alto.
