This LPIC-2 practice question tests your understanding of network client management. 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.
Which file is used to configure the LDAP client for system authentication on a modern Linux system using nss-pam-ldapd?
/etc/openldap/ldap.conf
Why wrong: Configuration for OpenLDAP client utilities, not system authentication.
/etc/nsswitch.conf
Why wrong: Defines name service order, not LDAP server details.
/etc/nslcd.conf
Correct file for nslcd daemon.
/etc/ldap.conf
Why wrong: Used by older nss_ldap, not modern nss-pam-ldapd.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
/etc/nslcd.conf
Option C is correct because /etc/nslcd.conf is the configuration file for nslcd, the LDAP name service daemon used by nss-pam-ldapd to perform LDAP queries for system authentication and user/group lookups. This daemon communicates with the LDAP server and provides the results to NSS and PAM modules, making it the central configuration point for LDAP client authentication on modern Linux systems.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
/etc/openldap/ldap.conf
Why it's wrong here
Configuration for OpenLDAP client utilities, not system authentication.
/etc/nsswitch.conf
Why it's wrong here
Defines name service order, not LDAP server details.
/etc/nslcd.conf
Why this is correct
Correct file for nslcd daemon.

/etc/ldap.conf
Why it's wrong here
Used by older nss_ldap, not modern nss-pam-ldapd.
Common exam traps
The trap here is that candidates often confuse /etc/nslcd.conf (used by nss-pam-ldapd) with /etc/ldap.conf (used by the older nss_ldap/pam_ldap) or /etc/openldap/ldap.conf (used by OpenLDAP client tools), leading them to select a wrong answer based on familiarity with a different LDAP client stack.
Detailed technical explanation
The nslcd daemon runs as a separate process that handles LDAP connections and caching, using the configuration in /etc/nslcd.conf to specify the LDAP URI, base DN, bind credentials, and TLS settings. This architecture improves reliability by isolating LDAP failures from the rest of the system, unlike the older nss_ldap which loaded the LDAP library directly into every process. In a real-world scenario, misconfiguring the 'uri' or 'base' directives in nslcd.conf can cause authentication failures that are logged in /var/log/messages or via the nslcd debug mode.
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 LPIC-2 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.
