| Check the group ownership of the Samba configuration 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 permissions include a "+", the file has an extended ACL and this is a finding. |

| Remove the extended ACL from the file: # getfacl /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf Remove each ACE returned: # setfacl -d [ACE] /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf |
