   A Samba server is a domain member. Windows users can authenticate, but when they try to access a share, they are prompted for credentials repeatedly. The administrator checks the logs and sees 'NT_STATUS_ACCESS_DENIED'. What is the most likely cause?

   • AThe 'obey pam restrictions' parameter is set to 'yes', and PAM is not configured to allow AD users.
   • BThe 'winbind offline logon' option is set to 'yes', and the domain controller is unreachable.
   • CThe 'server signing' parameter is set to 'mandatory', and the client does not support signing.
   • DThe 'ntlm auth' parameter is set to 'no', and the client is trying to use NTLM authentication.

   A Samba server is a domain member. Windows users can authenticate and access shares, but when they create new files, the files are owned by 'nobody' and other users cannot read them. The administrator checks the share definition and sees 'force user = nobody'. What is the most likely cause and the best fix?

   • AThe winbind service is not running, so Samba cannot map the authenticated user to a local UID. Start winbind and restart Samba.
   • BThe 'create mask' is set to 000, preventing other users from reading new files. Change 'create mask' to 0644.
   • CThe filesystem does not support POSIX ACLs. Remount the filesystem with the 'acl' option.
   • DThe 'force user' parameter is overriding the authenticated user's identity. Remove 'force user = nobody' from the share definition.

   A Samba server is not visible in the Windows Network Neighborhood. Other Samba servers are visible. The administrator checks the smb.conf and sees 'local master = no'. What is the most likely reason the server is not visible?

   • AThe 'wins support = yes' setting is missing, so the server cannot register its NetBIOS name.
   • BThe 'server string' is not set, so the server has no description in the browse list.
   • CThe 'local master = no' setting prevents the server from participating in browser elections, so it may not be advertised in the browse list.
   • DThe 'browseable = yes' setting is missing from the share definitions.

   A Samba server is configured in 'ads' security mode and is a domain member. Windows users can authenticate, but Linux users cannot access shares using their AD credentials. The administrator wants to allow Linux users to authenticate with their AD usernames and passwords. What is the most likely missing configuration?

   • AThe 'winbind use default domain = yes' option is missing, so Linux users must specify the domain when authenticating.
   • BThe 'map to guest = Bad User' option is set, causing all failed authentications to be mapped to the guest account.
   • CThe 'obey pam restrictions = yes' option is set, and PAM is not configured to allow AD users.
   • DThe 'security = ads' option is set, but 'password server' is not specified, so Samba cannot contact the AD domain controller.
