Cannot connect to samba share
 
Fairly new Linux user, running Fedora 12, attempting to set up a simple Samba share to share files with a Windows box. I've gotten to the point where I can connect from the Windows box, and see a home directory and the directory I'm trying to share. The home directory is accessible and works as expected, but when I try to access the other directory I get "The network path could not be found." In the Samba log, I see:

Code:

[2010/06/17 23:53:59,  0] smbd/service.c:988(make_connection_snum)
  canonicalize_connect_path failed for service Emulation, path /media/MAME/Emulation

Permissions for the shared directory are:
Code:

drwxrwxr-x. 11 MAMEuser MAMEuser 4096 2010-05-25 08:45 /media/MAME/Emulation
SELinux is disabled.

smb.conf is as follows:
Code:

# This is the main Samba configuration file. For detailed information about the
# options listed here, refer to the smb.conf(5) manual page. Samba has a huge
# number of configurable options, most of which are not shown in this example.
#
# The Official Samba 3.2.x HOWTO and Reference Guide contains step-by-step
# guides for installing, configuring, and using Samba:
# http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# The Samba-3 by Example guide has working examples for smb.conf. This guide is
# generated daily: http://www.samba.org/samba/docs/Samba-Guide.pdf

# In this file, lines starting with a semicolon (;) or a hash (#) are
# comments and are ignored. This file uses hashes to denote commentary and
# semicolons for parts of the file you may wish to configure.
#
# Note: Run the "testparm" command after modifying this file to check for basic
# syntax errors.
#
#---------------
# Security-Enhanced Linux (SELinux) Notes:
#
# Turn the samba_domain_controller Boolean on to allow Samba to use the useradd
# and groupadd family of binaries. Run the following command as the root user to
# turn this Boolean on:
# setsebool -P samba_domain_controller on
#
# Turn the samba_enable_home_dirs Boolean on if you want to share home
# directories via Samba. Run the following command as the root user to turn this
# Boolean on:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory, such as a new top-level directory, label it
# with samba_share_t so that SELinux allows Samba to read and write to it. Do
# not label system directories, such as /etc/ and /home/, with samba_share_t, as
# such directories should already have an SELinux label.
#
# Run the "ls -ldZ /path/to/directory" command to view the current SELinux
# label for a given directory.
#
# Set SELinux labels only on files and directories you have created. Use the
# chcon command to temporarily change a label:
# chcon -t samba_share_t /path/to/directory
#
# Changes made via chcon are lost when the file system is relabeled or commands
# such as restorecon are run.
#
# Use the samba_export_all_ro or samba_export_all_rw Boolean to share system
# directories. To share such directories and only allow read-only permissions:
# setsebool -P samba_export_all_ro on
# To share such directories and allow read and write permissions:
# setsebool -P samba_export_all_rw on
#
# To run scripts (preexec/root prexec/print command/...), copy them to the
# /var/lib/samba/scripts/ directory so that SELinux will allow smbd to run them.
# Note that if you move the scripts to /var/lib/samba/scripts/, they retain
# their existing SELinux labels, which may be labels that SELinux does not allow
# smbd to run. Copying the scripts will result in the correct SELinux labels.
# Run the "restorecon -R -v /var/lib/samba/scripts" command as the root user to
# apply the correct SELinux labels to these files.

# elections. The default value should be reasonable.

#----------------------------- Name Resolution -------------------------------
#
# This section details the support for the Windows Internet Name Service (WINS).

# server.
#
# wins server = tells the NMBD component of Samba to be a WINS client.
#
# wins proxy = when set to yes, Samba answers name resolution queries on behalf
# of a non WINS capable client. For this to work, there must be at least one
# WINS server on the network. The default is no.

# nslookups.

# --------------------------- Printing Options -----------------------------
#
# The options in this section allow you to configure a non-default printing
# system.
#
# load printers = when set you yes, the list of printers is automatically
# loaded, rather than setting them up individually.
#
# cups options = allows you to pass options to the CUPS library. Setting this
# option to raw, for example, allows you to use drivers on your Windows clients.

# printcap name = used to specify an alternative printcap file.

# --------------------------- File System Options ---------------------------
#
# The options in this section can be un-commented if the file system supports
# extended attributes, and those attributes are enabled (usually via the
# "user_xattr" mount option). These options allow the administrator to specify
# that DOS attributes are stored in extended attributes and also make sure that
# Samba does not change the permission bits.
#
# Note: These options can be used on a per-share basis. Setting them globally
# (in the [global] section) makes them the default for all shares.

Any suggestions will be greatly appreciated. I've hunted all over the web, tried a half dozen different things, cursed fluently, and ripped out big handfuls of hair, and I still have no clue what I'm doing wrong.

What does the output of testparm say? This command is useful to see if your configuration is correct.

1.add samba user:
#smbpasswd -a MAMEuser
New SMB password: (input your samba password,not linux user password)

2.
[Emulation]
path = /media/MAME/Emulation
public = yes
writeable = no
browseable = yes
valid users = MAMEuser

3.test on linux server
smbclient -L //localhost
smbclient //localhost/Emulation -U MAMEuser

OK, that works. Thanks!

Just for the sake of understanding what's going on here, why does the user "dmalaguti" that I created not have access to this directory? If I understand the permissions correctly, non-owners should have read and execute permissions. Are there other permissions that need to be set elsewhere?

My english is poor.Perhaps i am not understand your meaning.
But i test it on my CentOS4 using your samba configuration,i can access /media/MAME/Emulation through dmalaguti user in my windows2003 client.
