I am trying to get SSO for my WIFI with Azure AD.
I created an Azure Enterprise Application and assigned Users.
I set up SSO in Fortigate.
I created a usergroup in Fortigate.
I created Policies to use that group for Wifi access
I added that group to the SSID
I set the Captive Portal to Disclaimer (for debug reasons) and when I accept the disclaimer, I am forwarded to login.microsoft.com - but there I get a certificate error because for some reason, Fortigate seems to replace the IDP certificate (that I of course added to the appliance) with the Fortigate Factory Certificate. I am at a loss here as I do not understand, where and why the certificate gets replaced... Can't find anything in the forums or anywhere online, I have been searching for 3 days now...

Here's a screenshot of the problem I am facing. This is where I am redirected after accepting the disclaimer in the captive portal...
Hi @benKettner,
Can you check which certificate you are using? Looks like you are using self-signed certificate for captive portal.
config user setting
show full
Regards,
Thanks for getting back to me. This is the output of the user settings:
Hi @benKettner,
Can you set the certificate as follows:
config user setting
set auth-ca-cert "Fortinet_CA_SSL"
end
You can refer to this article at step 7: https://community.fortinet.com/t5/FortiGate/Technical-Tip-Wireless-Authentication-using-SAML-Credent...
Regards,
Unfortunately that did not change anything except that the cert is now set in the user settings.
The problem was solved in a support call today. The solution was that the policy that contained the MS SSO URLs as Addresses and was Portal Exempt did not work - we changed it to "Services Azure" and then SSO started working. Weird, that was the last place I would have looked for the problem...
Hello,
I'm having this same problem, could you explain to me in more detail how you solved it?
Regards
