Problema con samba

hola Tzhed\ Kyperf/, gracias por la respuesta , te comento que ya revise la configuracion del smb.conf y no le encuentro nada raro.. y es q lo complicado es q se puede ver la carpeta pero no se ven los cambios q realiza otro usuario

agradezco hasta el infinito cualquier colaboracion

smb.conf:

[global]

# ----------------------- Network Related Options -------------------------
#
# workgroup = NT-Domain-Name or Workgroup-Name, eg: MIDEARTH
#
# server string is the equivalent of the NT Description field
#
# netbios name can be used to specify a server name not tied to the hostname
#
# Interfaces lets you configure Samba to use multiple interfaces
# If you have multiple network interfaces then you can list the ones
# you want to listen on (never omit localhost)
#
# Hosts Allow/Hosts Deny lets you restrict who can connect, and you can
# specifiy it as a per share option as well
#
   workgroup = grupoE5150
   server string = Samba Server Version %v

;   netbios name = MYSERVER

;   interfaces = lo eth0 192.168.12.2/24 192.168.13.2/24
;   hosts allow = 127. 192.168.12. 192.168.13.

# --------------------------- Logging Options -----------------------------
#
# Log File let you specify where to put logs and how to split them up.
#
# Max Log Size let you specify the max size log files should reach

   # logs split per machine
;   log file = /var/log/samba/%m.log
   # max 50KB per log file, then rotate
;   max log size = 50

# ----------------------- Standalone Server Options ------------------------
#
# Security can be set to user, share(deprecated) or server(deprecated)
#
# Backend to store user information in. New installations should
# use either tdbsam or ldapsam. smbpasswd is available for backwards
# compatibility. tdbsam requires no further configuration.

   security = user
   passdb backend = tdbsam

# ----------------------- Domain Members Options ------------------------
#
# Security must be set to domain or ads
#
# Use the realm option only with security = ads
# Specifies the Active Directory realm the host is part of
#
# Backend to store user information in. New installations should
# use either tdbsam or ldapsam. smbpasswd is available for backwards
# compatibility. tdbsam requires no further configuration.
#
# Use password server option only with security = server or if you can't
# use the DNS to locate Domain Controllers
# The argument list may include:
# password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]
# or to auto-locate the domain controller/s
# password server = *

;   security = domain
;   passdb backend = tdbsam
;   realm = MY_REALM

;   password server = <NT-Server-Name>

# ----------------------- Domain Controller Options ------------------------
#
# Security must be set to user for domain controllers
#
# Backend to store user information in. New installations should
# use either tdbsam or ldapsam. smbpasswd is available for backwards
# compatibility. tdbsam requires no further configuration.
#
# Domain Master specifies Samba to be the Domain Master Browser. This
# allows Samba to collate browse lists between subnets. Don't use this
# if you already have a Windows NT domain controller doing this job
#
# Domain Logons let Samba be a domain logon server for Windows workstations.
#
# Logon Scrpit let yuou specify a script to be run at login time on the client
# You need to provide it in a share called NETLOGON
#
# Logon Path let you specify where user profiles are stored (UNC path)
#
# Various scripts can be used on a domain controller or stand-alone
# machine to add or delete corresponding unix accounts
#
;   security = user
;   passdb backend = tdbsam

;   domain master = yes
;   domain logons = yes

   # the login script name depends on the machine name
;   logon script = %m.bat
   # the login script name depends on the unix user used
;   logon script = %u.bat
;   logon path = \\%L\Profiles\%u
   # disables profiles support by specifing an empty path
;   logon path =

;   add user script = /usr/sbin/useradd "%u" -n -g users
;   add group script = /usr/sbin/groupadd "%g"
;   add machine script = /usr/sbin/useradd -n -c "Workstation (%u)" -M -d /nohome -s /bin/false "%u"
;   delete user script = /usr/sbin/userdel "%u"
;   delete user from group script = /usr/sbin/userdel "%u" "%g"
;   delete group script = /usr/sbin/groupdel "%g"

# ----------------------- Browser Control Options ----------------------------
#
# set local master to no if you don't want Samba to become a master
# browser on your network. Otherwise the normal election rules apply
#
# OS Level determines the precedence of this server in master browser
# elections. The default value should be reasonable
#
# Preferred Master causes Samba to force a local browser election on startup
# and gives it a slightly higher chance of winning the election
;   local master = no
;   os level = 33
;   preferred master = yes

#----------------------------- Name Resolution -------------------------------
# Windows Internet Name Serving Support Section:
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
#
# - WINS Support: Tells the NMBD component of Samba to enable it's WINS Server
#
# - WINS Server: Tells the NMBD components of Samba to be a WINS Client
#
# - WINS Proxy: Tells Samba to answer 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.
#
# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups.

;   wins support = yes
;   wins server = w.x.y.z
;   wins proxy = yes

;   dns proxy = yes

# --------------------------- Printing Options -----------------------------
#
# Load Printers let you load automatically the list of printers rather
# than setting them up individually
#
# Cups Options let you pass the cups libs custom options, setting it to raw
# for example will let you use drivers on your Windows clients
#
# Printcap Name let you specify an alternative printcap file
#
# You can choose a non default printing system using the Printing option

   load printers = yes
   cups options = raw

;   printcap name = /etc/printcap
   #obtain list of printers automatically on SystemV
;   printcap name = lpstat
;   printing = cups

# --------------------------- Filesystem Options ---------------------------
#
# The following options can be uncommented if the filesystem supports
# Extended Attributes and they are enabled (usually by the mount option
# user_xattr). Thess options will let the admin store the DOS attributes
# in an EA and make samba not mess with the permission bits.
#
# Note: these options can also be set just per share, setting them in global
# makes them the default for all shares

;   map archive = no
;   map hidden = no
;   map read only = no
;   map system = no
;   store dos attributes = yes
