Question 300
A FortiOS 7.6 team examines: One user belongs to the correct directory group but the RADIUS group attribute does not match the firewall mapping. Select TWO complementary choices: the most appropriate corrective action AND the specific evidence confirming success.
Explanation
Correct Answers
The reported FortiOS 7.6 condition is: One user belongs to the correct directory group but the RADIUS group attribute does not match the firewall mapping. The targeted administrative response is: Validate FortiGate RADIUS server settings, shared secrets, authentication reachability and approved group response attributes. The relevant failure risk is: A mismatched secret or unreachable RADIUS source may reject every legitimate login regardless of user password. Validate with: A controlled authentication request receives the expected accept or reject result and maps policy groups correctly.
For the observed situation (One user belongs to the correct directory group but the RADIUS group attribute does not match the firewall mapping), the most specific acceptance evidence is: A controlled authentication request receives the expected accept or reject result and maps policy groups correctly. It validates the recommended response: Validate FortiGate RADIUS server settings, shared secrets, authentication reachability and approved group response attributes. This addresses the documented risk: A mismatched secret or unreachable RADIUS source may reject every legitimate login regardless of user password.
Incorrect Answers
Central snat versus policy nat selection (2.2) would demonstrate or implement: Changing only firewall-policy NAT settings when central NAT is authoritative can leave the source address unchanged. The case states: One user belongs to the correct directory group but the RADIUS group attribute does not match the firewall mapping. The most direct paired action and test is: Validate FortiGate RADIUS server settings, shared secrets, authentication reachability and approved group response attributes.
Interface-based source nat for outbound clients (2.2) addresses another technical failure: Without correct source translation and return routing, private-address internet sessions may fail despite an allow rule. The required paired action and test concerns Radius authentication and shared secret checks; a passing result for this alternative could leave that requirement unresolved.
Address objects and policy scope (2.1) would demonstrate or implement: Test clients from included and excluded subnets reach only the intended destinations and policy hit counters align. The paired-answer requirement concerns Radius authentication and shared secret checks; this alternative does not provide the matching intervention and separate acceptance evidence.
