NAME

       samba_selinux - Security Enhanced Linux Policy for Samba

DESCRIPTION

       Security-Enhanced Linux secures the Samba server via flexible mandatory access control.

FILE_CONTEXTS
       SELinux	requires  files to have an extended attribute to define the file type.	Policy governs the access daemons have to these files.	If
       you want to share files other than home directories, those files must be labeled samba_share_t.	So if  you  created  a	special  directory
       /var/eng, you would need to label the directory with the chcon tool.

       chcon -t samba_share_t /var/eng

       To make this change permanent (survive a relabel), use the semanage command to add the change to file context configuration:

       semanage fcontext -a -t samba_share_t "/var/eng(/.*)?"

       This command adds the following entry to /etc/selinux/POLICYTYPE/contexts/files/file_contexts.local:

       /var/eng(/.*)? system_u:object_r:samba_share_t:s0

       Run the restorecon command to apply the changes:

       restorecon -R -v /var/eng/

SHARING FILES

       If  you	want  to  share  files	with multiple domains (Apache, FTP, rsync, Samba), you can set a file context of public_content_t and pub-
       lic_content_rw_t.  These context allow any of the above domains to read the content.  If you want a particular domain to write to the  pub-
       lic_content_rw_t domain, you must set the appropriate boolean.  allow_DOMAIN_anon_write.  So for samba you would execute:

       setsebool -P allow_smbd_anon_write=1

BOOLEANS

       SELinux	policy is customizable based on least access required.	So by default SELinux policy turns off SELinux sharing of home directories
       and the use of Samba shares from a remote machine as a home directory.

       If you are setting up this machine as a Samba server and wish to share the home directories, you need  to  set  the  samba_enable_home_dirs
       boolean.

	      setsebool -P samba_enable_home_dirs 1

       If you want to use a remote Samba server for the home directories on this machine, you must set the use_samba_home_dirs boolean.

	      setsebool -P use_samba_home_dirs 1

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
