samba for windows user sharing

I setup a samba server in RHEL 6, sharing /home, the format of the partition is ext4, can samba shares ext4 to windows ??

When I share /tmp, I can do all the user security settings, but when I share a folder under /home with the same setting as /tmp, no user can access.

any idea ??

Can You post Your smb.conf file?

l# 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:
# Many working examples of smb.conf files can be found in the
# Samba-Guide which is generated daily and can be downloaded from:
# 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.
# 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

# - WINS Proxy: Tells Samba to answer name resolution queries on
#   behalf of a non WINS capable client, for this to work there must be

# --------------------------- Filesystem Options ---------------------------

# Extended Attributes and they are enabled (usually by the mount option

Just a notice when You use 'unix password sync' parameter You need to set 'passwd program' parameter like. By default it will use passwd.

Except for that it seems valid.

Can You post me permissions and owners of the directories /home/Mark and /tmp ?

So it's clear now. The trailing dot show that You're using SELinux.

Please try to run this command
setsebool -P samba_enable_home_dirs 1

By default SELinux is protecting the home directory from being shared.
