Question 290
A FortiOS 7.6 team examines: A supported directory user exists but the FortiGate lookup base excludes the user organizational unit. 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: A supported directory user exists but the FortiGate lookup base excludes the user organizational unit. The targeted administrative response is: Configure FortiGate LDAP connectivity, bind permissions and approved group lookup for required user authentication flows. The relevant failure risk is: A working network route to the directory does not prove bind credentials or group attribute mappings are valid. Validate with: An approved directory test user authenticates and maps to the intended access group while invalid credentials fail.
For the observed situation (A supported directory user exists but the FortiGate lookup base excludes the user organizational unit), the most specific acceptance evidence is: An approved directory test user authenticates and maps to the intended access group while invalid credentials fail. It validates the recommended response: Configure FortiGate LDAP connectivity, bind permissions and approved group lookup for required user authentication flows. This addresses the documented risk: A working network route to the directory does not prove bind credentials or group attribute mappings are valid.
Incorrect Answers
Firewall policy logging and traceability (2.1) addresses another technical failure: Without consistent allowed and denied event visibility, teams cannot determine which policy produced an outage. The case states: A supported directory user exists but the FortiGate lookup base excludes the user organizational unit. The most direct paired action and test is: Configure FortiGate LDAP connectivity, bind permissions and approved group lookup for required user authentication flows.
Implicit deny and least privilege (2.1) would demonstrate or implement: Approved protocol tests succeed while unmatched source, destination and service combinations are denied and logged as configured. This choice can be useful for that problem, but it does not establish the Ldap directory authentication configuration control being assessed here.
Virtual IP destination nat for inbound services (2.2) would demonstrate or implement: A configured VIP without a matching permit or correct port mapping does not make the backend reachable securely. The paired-answer requirement concerns Ldap directory authentication configuration; this alternative does not provide the matching intervention and separate acceptance evidence.
