LPIC-2 File Sharing and Samba Practice Question
Which THREE configuration directives are necessary to enable Winbind for Active Directory authentication on a Samba domain member?
⚠ Common exam trap
Candidates often confuse 'workgroup' with 'realm' or assume 'winbind use default domain = yes' is mandatory, when in fact only 'security = ads', 'realm', and an idmap range are strictly required for basic Winbind AD integration.

Correct answer & explanation
✓
security = ads
Setting 'security = ads' tells Samba to operate as an Active Directory domain member, using Kerberos for authentication and LDAP for identity lookups. This directive is mandatory for Winbind to communicate with an AD domain controller.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
security = ads
Why this is correct
Correct; enables Active Directory domain membership.
- ✗
winbind use default domain = yes
Why it's wrong here
Incorrect; optional, simplifies username format.
- ✓
realm = EXAMPLE.COM
Why this is correct
Correct; specifies the Kerberos realm for authentication.
- ✗
workgroup = EXAMPLE
Why it's wrong here
Incorrect; while often set, it is not strictly required if netbios name matches, but still needed in practice. However, for this question we omit it.
- ✓
idmap config * : range = 10000-20000
Why this is correct
Correct; defines the UID/GID range for ID mapping.
