Captive Portal Authentication for Non Domain users using FSSO

[Zaheerudin45]

Hello Community,

I’m working on configuring Captive Portal on my FortiGate firewall with FSSO integration, and I’d appreciate some guidance.

Objective:

• Domain users should be authenticated automatically via FSSO (or group-based policies) when they are on the corporate network.

• Non-domain users (not logged into the domain) should be redirected to the Captive Portal.

• On the Captive Portal page, these non-domain users should still be able to log in using their Active Directory credentials (username/password) to access the internet.

Is there a recommended approach or workaround to achieve this setup?

Thanks in advance!
