Check Text ( C-38910r4_chk )

Check the group ownership 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 -l /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf If an smb.conf file is not group-owned by root, bin, or sys, this is a finding.

Fix Text (F-34290r4_fix)
Change the group owner of the smb.conf file. Procedure: # chgrp root /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf
