LPIC-2 username map Practice Question
Which TWO of the following are valid ways to map a Windows user to a Linux account in Samba?
⚠ Common exam trap
Candidates often confuse 'force user' (which overrides the authenticated user for file operations) with a mapping mechanism, when in fact it does not map Windows users to Linux accounts but instead forces all connections to run as a specific Linux user.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Using a 'username map' file specified by the 'username map' parameter
The 'username map' parameter in smb.conf specifies a file (e.g., /etc/samba/smbusers) that maps Windows usernames to Linux usernames, allowing Samba to translate incoming Windows user credentials to a corresponding Linux account. Option B is correct because 'force user' in a share definition forces all connections to that share to run as a specific Linux user, effectively mapping any Windows user to that Linux account for file operations. Both are valid ways to map Windows users to Linux accounts in Samba.
