+# This is the main Samba configuration file. You should read the
+# smb.conf(5) manual page in order to understand the options listed
+# here. Samba has a huge number of configurable options (perhaps too
+# many!) most of which are not shown in this example
+#
+# For a step to step guide on installing, configuring and using samba, 
+# read the Samba-HOWTO-Collection. This may be obtained from:
+#  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
+#
+# Many working examples of smb.conf files can be found in the 
+# Samba-Guide which is generated daily and can be downloaded from: 
+#  http://www.samba.org/samba/docs/Samba-Guide.pdf
+#
+# Any line which starts with a ; (semi-colon) or a # (hash) 
+# is a comment and is ignored. In this example we will use a #
+# for commentry and a ; for parts of the config file that you
+# may wish to enable
+#
+# NOTE: Whenever you modify this file you should run the command "testparm"
+# to check that you have not made any basic syntactic errors.

+#---------------
+# SELINUX NOTES:
+#
+# If you want to use the useradd/groupadd family of binaries please run:
+# setsebool -P samba_domain_controller on
+#
+# If you want to share home directories via samba please run:
+# setsebool -P samba_enable_home_dirs on
+#
+# If you create a new directory you want to share you should mark it as
+# "samba_share_t" so that selinux will let you write into it.
+# Make sure not to do that on system directories as they may already have
+# been marked with othe SELinux labels.
+#
+# Use ls -ldZ /path to see which context a directory has
+#
+# Set labels only on directories you created!
+# To set a label use the following: chcon -t samba_share_t /path
+#
+# If you need to share a system created directory you can use one of the
+# following (read-only/read-write):
+# setsebool -P samba_export_all_ro on
+# or
+# setsebool -P samba_export_all_rw on
+#
+# If you want to run scripts (preexec/root prexec/print command/...) please
+# put them into the /var/lib/samba/scripts directory so that smbd will be
+# allowed to run them.
+# Make sure you COPY them and not MOVE them so that the right SELinux context
+# is applied, to check all is ok use restorecon -R -v /var/lib/samba/scripts

+#   behalf of a non WINS capable client, for this to work there must be
