FortiAuthenticator and RHEL Server Integration for MFA and authenticate to AD Users

Hello Anyone and Experts,

Could you please help me and advise me anything about integration between FortiAuthenticator and RHEL Server integraton for MFA to AD Users?

Actually I follow below article for linux integration but it does not working.

FortiAuthenticator version: 6.6.2

RHEL OS version: 9.4

Thanks,

Hi Leo

What do you see in FAC's authentication logs?

Also, a good idea is to try first doing without MFA and once it work then add MFA.

Hi AEK,

Thanks for your reply there is I can ping to my FortiAuthenticator but cannot see any radius request is coming from RHEL Server.

I think that RHEL has some restrictions and I have no idea how can I resolve this.

Could you please advise?

Thanks,

Hi Leo

Is there a firewall between your RHEL and FAC? If so the check if the RADIUS traffic is allowed, and check if the firewall can actually see this traffic
Check if RHEL's firewall is blocking the RADIUS traffic
Use tcpdump on your RHEL to see if the RADIUS requests are actually being sent from your RHEL. Also check if they are sent from the right server port and with the right source IP and destination IP

Once you share the result we may help further.
