Hi
Is there any way to add a secondary radius server on Fortimail 400F running code 7.2.6, for Admin authentication?

Thanks in advance.

Hi

Did you try from CLI?

 

config profile authentication radius
  edit rad1

    ...

  next

  edit rad2
    ...
  next
end

I didn't test it but I think it should work.

BTW you can add multiple RADIUS servers on FML WebUI as well:

But if you mean by secondary RADIUS server a backup RADIUS server (in case 1st doesn't respond the second is requested), then I don't find such possibility in FML CLI, that means it is not implemented (yet).

Hi,
Thanks for the input.
So, this is the way of doing it! It's different from other fortinet products where we can add 2 rad_srv (primary & backup) in a single rad profile.
However, if I go for this approach, the remote user will be assigned to one rad profile only!. How to overcome this issue?

In this case I guess a solution is to use a load balancer, or a RADIUS cluster in A-P HA.
