Palo Alto RADIUS authentication against Microsoft NPS is broken

L2 Linker

Has anyone managed to get authentication on PAN-OS 7.0 working with microsoft NPS servers?

 

Since version 7.0 authentication against our microsoft NPS radius servers is broken. Because the firewall now always first tries CHAP instead op PAP (see this article) and microsoft NPS always replies with a ACCESS-REJECT massage (see this article -> item 9).

 

As it's insane to start storing our AD credentials with reversible encryption I guess microsoft NPS isn't compatible anymore with Palo Alto? Or am I missing something here?

What is the PAN-OS on the firewall?

It will work on PAN-OS 7.0.4. You dont have to go in configure mode.

 

admin@fw63> set authentication radius-auth-type chap

 

Hope this helps!

 

Merry Christmas 🙂
