Quick Answer
The answer is that the LDAP bind account does not have permission to read group attributes. When users can authenticate but group membership information is not retrieved, the bind account itself lacks the necessary read rights on the LDAP directory’s group objects, preventing the FortiGate from resolving which groups a user belongs to. This scenario tests your understanding of LDAP integration on the Fortinet NSE 4 Network Security Professional exam, specifically how bind credentials and attribute mappings like 'cn' or 'member' must align with directory permissions. A common trap is assuming authentication success means group retrieval will work, but the bind account is a separate service account that requires explicit read access to group attributes. To remember this, think: “Auth works, groups don’t? Check the bind account’s read rights.”
This NSE4 practice question tests your understanding of authentication and vpn. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator configures an LDAP user group for firewall authentication. Users are able to authenticate, but the FortiGate does not retrieve group membership information. What is likely misconfigured?
The LDAP server's IP address is incorrect
Why wrong: If authentication works, connectivity is fine.
SSL is not enabled for LDAP
Why wrong: SSL encryption is optional for group retrieval.
The LDAP bind account does not have permission to read group attributes
Group membership retrieval requires read access to group objects.
The FortiGate is not joined to the domain
Why wrong: LDAP authentication does not require domain join.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The LDAP bind account does not have permission to read group attributes
The LDAP server must be configured with the correct bind credentials and search filter to retrieve group memberships. The 'cn' or 'member' attribute mapping is also critical.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

SSL is not enabled for LDAP
Why it's wrong here
SSL encryption is optional for group retrieval.
The LDAP bind account does not have permission to read group attributes
Why this is correct
Group membership retrieval requires read access to group objects.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the NSE4 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
