We have the below assets:

  • Windows CA
  • FortiNAC-VM
  • Fortigate-40F
  • FortiSwitch-108F-POE
  • FortiAP 221E

We are trying to setup the Corporate WiFi Access with FortiNAC, using a certificate. 

Flow:
Users must Connect to an SSID with WPA2 Enterprise and FortiNAC confirms a user as corporate with certificate checking. 

 

We did all the steps we know and when a test pc try to connect in the Corporate SSID, we take the FortiNAC-RADIUS error below: 

  • Auth: (93) Login incorrect (RADIUS not enabled on device (Post-Auth)):

What is the issue resolving path?

Hi! 

We test version 7.2.9 and FortiNAC service is working fine. 

Thanks for your replies!


P.S.: I believe Fortinet should have create an analytical Installation Guide with basic use-cases examples.

The issue may be related to fix 1129743 which is going to be included in the next release of 7.4.2 (published next week) and is already included in the latest version of 7.6.3, some details are included in the release notes.
