I can´t access my share on ubuntu system

I have Ubuntu server 10 and I can see my windows share on it, but I´m not accessing. User and password aren´t allowed to access it. How can I login ?
I have samba and webmin installed.

Hi, did you try with smbclient?
Jose BredariolPMPAuthor Commented:
no, i've tried with windows explorer at address bar I type the Linux IP and browse the shared folder. When I click on the shared folder I have to put username and password. After that I received an error message. Username and password are denied.
So the share is on Ubuntu? I don't think you want to call it a "Windows Share" then. So the permissions to allow you to enter it would be being checked by Ubuntu, therefore you need to enter your Ubuntu username and password, not your Windows credentials.

Your question, your audience. Choose who sees your identity—and your question—with question security.

Jose BredariolPMPAuthor Commented:
Yes, I´m using my ubuntu credentials, but I´m not getting access. I create a new ubuntu user and test it too, but nothing.
See this guide about half way down. You may need to enter your Ubuntu hostname followed by a backslash (\) then the Ubuntu username.
Did you add a password using smbpasswd?  
Jose BredariolPMPAuthor Commented:
No, How can I use that ?
Read the man page for smbpasswd.

  $ smbpasswd userid
Jose BredariolPMPAuthor Commented:
I did it :
sudo smbpasswd -a userxxx
sudo pass :
New SMB pass
retype SMB pass
I´m receiving :Failed to find entry for user userxxx

What I´m doing wrong ?
Is userxxx a valid Linux user id?  If not, create an account.
Jose BredariolPMPAuthor Commented:
Yes, I create this accout with adduser userxxx
Jose BredariolPMPAuthor Commented:
here whats´happening :

admsmdxxx@xxxubuntusr10:~$ sudo smbpasswd userxxx
New SMB password:
Retype new SMB password:
Failed to find entry for user userxxx.
Jose BredariolPMPAuthor Commented:
Sorry, I was wrong.

sudo smbpasswd -a  userxxx
I created the userxxx sucessfully.
In windows 7 machine while creating the network drive, I received an error :

The X:\ isn´t available
Acess denied
Please post your /etc/samba/smb.conf.

# Sample configuration file for the Samba suite for Debian GNU/Linux.
# 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 most of which
# are not shown in this example
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.

# interface names are normally preferred

# Only bind to the named interfaces and/or networks; you must use the

#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
#   syslog only = no

####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.

# You may wish to use password encryption.  See the section on
# 'encrypt passwords' in the smb.conf(5) manpage before enabling.

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.  

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections

Add "security = user" to the smb.conf file and restart smbd.

Where did you add "security = user"?  

How did you restart Samba?

What directory are you trying to mount?  

What is the user id?  

You may need to specify the workgroup in valid users:
  valid users = '@SBADUAL\useradmubuntuxxx'
Jose BredariolPMPAuthor Commented:
Where did you add "security = user"?   at Global settings
How did you restart Samba? I restart the server
What directory are you trying to mount?  The directory was mounted, I can saw it on my linux desktop.
What is the user id?
uid=1000(admsmd) gid=0(root) groups=0(root),4(adm),20(dialout),24(cdrom),46(plugdev),112(lpadmin),115(libvirtd),117(sambashare),120(admin),1000(admsmd),1002(grpadmubuntu),1003(smb)
You may need to specify the workgroup in valid users: I didn´t understand - My windows 7 log on at  a domain.
What is the name of the user on the Windows machine?

What is the name of the share which you are trying to access from Windows?

The last line in your smb.conf gives the name of the valid user for the BiblioWin share.  You may need to specify the domain/workgroup name instead of just the user name.  

If you go to browse the Samba server, what shares does it say is available?
Jose BredariolPMPAuthor Commented:
What is the name of the user on the Windows machine? Joseph breda

What is the name of the share which you are trying to access from Windows?
On windows explorer I can see bibliowin (shared) at linux server or on linux Ip on address bar

The last line in your smb.conf gives the name of the valid user for the BiblioWin share.  You may need to specify the domain/workgroup name instead of just the user name
Are you saying I have to add at the last line : ,SBADUAL/joseph breda

At webmin on samba windows file sharing I have :
Bibliowin -  /media/compartilharwin - read only to every one
The only users permitted to access bibliowin is useradmubuntuxxx.  

Is this the name you gave when using smbpasswd?  

Try mounting the share using this as an alternate user name.  
Jose BredariolPMPAuthor Commented:
I dont undertans, can you explain in details ?
See the tutorial which cyclechip mentioned: http://www.7tutorials.com/how-access-ubuntu-shared-folders-windows-7

Look for "Access Ubuntu Shared Folders from Windows 7".

The userid which you use on Windows to access the shared directory must be the same as the userid which you specify to smbpasswd.  
Jose BredariolPMPAuthor Commented:
Nothing yet, look what I did :
1) In my windows i log with : user : Joseph breda - Password : xxxyyy - Domain : SBADUAL
2) In linux I added the user jbreda (because I can´t use space) with useradd and after that I use the command smbpasswd -a jbreda. In all cases I use the same password: xxxyyy
3) restart
4) testparm result :
load smb config files from /etc/samba/smb.conf

6) Right click on it - map network drive.

8)) I tried : sbaubuntusr10\jbreda - password : xxxyyy
The drive was mapped but i cant access it.

Jose BredariolPMPAuthor Commented:
My ubuntu is :

Your smb configuration says that the only users who can access the Bibliowin are useradmubuntu , jbredariol, and members of the @admsmd group.  If you are logging in with a different user id, access is denied.

Either use one of the valid user ids or add the one you want to use to the valid user list.

With Samba, four things need to be in sync:  the Linux userid, the smbpasswd, the valid user list, and the usrid you use to mount the share.
