       samba_selinux - Security Enhanced Linux Policy for Samba

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

       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/con-

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

       Run the restorecon command to apply the changes:

       restorecon -R -v /var/eng/

       If you want to share files with multiple domains (Apache,  FTP,  rsync,
       Samba),  you can set a file context of public_content_t and public_con-
       tent_rw_t.  These context allow any of the above domains  to  read  the
       content.   If  you want a particular domain to write to the public_con-
       tent_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

       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

              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 pol-
       icy settings.
