Question 470
At Fairmont Insurance, the FortiGate 7.6 security administration team encounters the following authorized operational case: a managed domain workstation receives repeated browser authentication prompts despite an available passive identity integration. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. What root condition most directly explains the described FortiGate symptom?
Explanation
Correct Answer
Passive identity mapping can associate an authenticated workstation user without requiring a repeated captive portal challenge. The mechanism is relevant because the stated passive sso versus captive portal incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to use a supported passive FSSO identity mapping rather than an interactive portal for eligible domain users; verify it through this observed condition: a signed-in domain user matches the expected user group without a new password prompt.
Incorrect Answers
One IP address alone cannot distinguish simultaneous user sessions on a shared terminal server explains a different situation, terminal server multi-user fsso, where several remote desktop users share one terminal-server IP and FortiGate incorrectly assigns them the same firewall identity. It does not account for the specific observed passive sso versus captive portal condition at Fairmont Insurance. The decisive mechanism here is: Passive identity mapping can associate an authenticated workstation user without requiring a repeated captive portal challenge.
A single identity collector creates a failure domain for otherwise healthy firewall policies explains a different situation, fsso collector redundancy, where firewall identity policies stop matching after the single FSSO collector host becomes unavailable. It does not account for the specific observed passive sso versus captive portal condition at Fairmont Insurance. The decisive mechanism here is: Passive identity mapping can associate an authenticated workstation user without requiring a repeated captive portal challenge.
Country-based address matching can differ from a partner's administrative location when egress IPs are elsewhere explains a different situation, geographic address policy exceptions, where legitimate partner traffic is blocked because a country address object was applied as a broad policy condition without verifying the partner's real egress. It does not account for the specific observed passive sso versus captive portal condition at Fairmont Insurance. The decisive mechanism here is: Passive identity mapping can associate an authenticated workstation user without requiring a repeated captive portal challenge.
