Check Text ( C-39146r2_chk )
Check the mode of the smb.conf file. Default locations for this file include /etc, /etc/sfw, /etc/samba, and /etc/sfw/samba. If the system has Samba installed in non-standard locations, also check the smb.conf in those locations.

Procedure:
# ls -lL /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf


If the smb.conf has a mode more permissive than 0644, this is a finding.
Fix Text (F-34291r2_fix)
Change the mode of the smb.conf file to 0644 or less permissive.

Procedure:
# chmod 0644 /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf
