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 a smb.conf file is not owned by root, this is a finding.

Fix Text (F-34289r2_fix)
Change the ownership of the smb.conf file. Procedure: # chown root /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf
