Question 490
At Greenridge University, the FortiGate 7.6 security administration team encounters the following authorized operational case: directory authentication fails only for employees moved into a different organizational unit. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. What root condition most directly explains the described FortiGate symptom?
Explanation
Correct Answer
LDAP searches do not find identities outside the configured base and filtering scope. The mechanism is relevant because the stated ldap search-base scope incident concerns the actual selected path, policy, identity or inspection state. The appropriate response is to expand the authorized LDAP search base or filter to include the intended directory subtree; verify it through this observed condition: both affected and previously valid user accounts are resolved without including prohibited groups.
Incorrect Answers
Passive identity tied to an address can be stale when endpoint addresses are reassigned quickly explains a different situation, roaming user stale ip mapping, where an employee moves from Ethernet to Wi-Fi and inherits another user's old FortiGate identity mapping. It does not account for the specific observed ldap search-base scope condition at Greenridge University. The decisive mechanism here is: LDAP searches do not find identities outside the configured base and filtering scope.
Agent-based and polling collection rely on different event acquisition paths and prerequisites explains a different situation, fsso polling versus dc agent mode, where a new domain-controller deployment fails to generate timely FSSO mappings because its chosen collection method cannot access the expected logon events. It does not account for the specific observed ldap search-base scope condition at Greenridge University. The decisive mechanism here is: LDAP searches do not find identities outside the configured base and filtering scope.
NGFW mode changes where applications and URL categories are matched, not merely the graphical presentation explains a different situation, profile-based versus policy-based ngfw, where a network team attempts to attach standalone application-control profiles exactly as before after switching a VDOM into policy-based NGFW mode. It does not account for the specific observed ldap search-base scope condition at Greenridge University. The decisive mechanism here is: LDAP searches do not find identities outside the configured base and filtering scope.
