Quick Answer
The answer is winbind, specifically the winbindd daemon. This Samba service is the correct choice because it acts as the bridge between a Linux system and a Windows Active Directory domain, resolving user and group information from the domain controller using Kerberos for authentication and LDAP for directory lookups. Without winbind, Samba can share files, but it cannot map Windows domain users to local Unix accounts, which is essential for true domain membership and single sign-on. On the LPIC-2 exam, this question tests your understanding of Samba’s modular architecture—many candidates mistakenly choose smbd or nmbd, but those handle file sharing and NetBIOS name resolution, not identity resolution. A common trap is confusing winbind with the security settings in smb.conf; remember that winbind is the service that actually talks to the domain controller. Memory tip: think “Winbind = Windows Bind,” as it binds the Linux system to the Active Directory domain.
This LPIC-2 practice question tests your understanding of file sharing and samba. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A company wants to use Samba to share files with Windows clients. Which service must be enabled in Samba to support Windows Active Directory domain membership?
nmbd
Why wrong: nmbd handles NetBIOS name service, not AD integration.
smbd
Why wrong: smbd provides file and print services, but not AD membership.
swat
Why wrong: swat is a web-based configuration tool, not a service for AD integration.
winbind
Winbind allows Samba to use Windows AD for authentication and identity mapping.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
winbind
Winbind (winbindd) is the Samba service that integrates with Windows Active Directory by resolving user and group information from the domain controller. It uses the Microsoft Active Directory authentication protocol (Kerberos) and LDAP to map Windows domain users to local Unix accounts, enabling domain membership and single sign-on.
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.
nmbd
Why it's wrong here
nmbd handles NetBIOS name service, not AD integration.
smbd
Why it's wrong here
smbd provides file and print services, but not AD membership.
swat
Why it's wrong here
swat is a web-based configuration tool, not a service for AD integration.
winbind
Why this is correct
Winbind allows Samba to use Windows AD for authentication and identity mapping.

Common exam traps
The trap here is that candidates often confuse the core file-sharing service (smbd) with the domain integration service (winbind), assuming smbd alone handles AD membership because it manages shares.
Detailed technical explanation
Winbind uses the idmap subsystem to map Windows SIDs to Unix UIDs/GIDs, and it relies on the 'security = ads' setting in smb.conf along with Kerberos tickets (obtained via 'kinit') to authenticate against Active Directory. A common real-world scenario is when winbind is not started or misconfigured, causing 'getent passwd' to return no domain users even though smbd and nmbd are running.
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.
