====== Setup a SMB Share with Multiple Users ======

Samba is a free software re-implementation of the SMB/CIFS networking protocol. Samba provides file and print services for various Microsoft Windows clients and can integrate with a Microsoft Windows Server domain. 

With this guide you will be able to create a SMB share with multiple users who can see and modify the files of other users without permissions issues. This can of course be changed so that only the individual users can see and modify their own files.


===== Setup SMB share =====
==== Installation ====

First install the samba package:

  sudo apt install samba

The configuration files are located at ''/etc/samba/smb.conf''


==== Directory Setup and Admin User Creation ====
This will be the base directory for directory containing the **users** folder. The **users** folder will contain all user directories.

  sudo mkdir /samba
  sudo chgrp sambashare /samba

This user will function as the user share admin, it is not necessary if you already have created a smb user with the same username who has sudo access. This user will not have shell access.

  sudo useradd -M -d /samba/users -s /usr/sbin/nologin -G sambashare sadmin

This is where the smb password is set.

  sudo smbpasswd -a sadmin

This is the **users** which will contain all of the user folders. We will set the permissions so that any of the members of the sambashare group will be able to view and modify files in this folder.

  sudo mkdir /samba/users
  sudo chown sadmin:sambashare /samba/users
  sudo chmod 2770 /samba/users

==== Creation of Individual Users ====

This will create the user "user1" with the home directory ''/samba/users/user1'', without shell access and add it to the sambashare group.

To add additional users, follow the same steps, //be sure to change all of the instances of **user1** to something else//.

  sudo useradd -M -d /samba/users/user1 -s /usr/sbin/nologin -G sambashare user1
  sudo mkdir /samba/users/user1
  sudo chown user1:sambashare /samba/users/user1
  sudo chmod 2770 /samba/users/user1
  sudo smbpasswd -a user1
  sudo smbpasswd -e user1





Edit the samba config file
''/etc/samba/smb.conf''

<code>
[users]
    path = /samba/users
    browseable = yes
    read only = no
    force create mode = 0660
    force directory mode = 2770
    valid users = @sambashare @sadmin

[user1]
    path = /samba/users/user1
    browseable = no
    read only = no
    force create mode = 0660
    force directory mode = 2770
    valid users = user1 @sadmin
    
#[user2]
#    path = /samba/users/user2
#    browseable = no
#    read only = no
#    force create mode = 0660
#    force directory mode = 2770
#    valid users = user2 @sadmin
</code>

==== Restart smbd Service ====

  sudo systemctl daemon-reload;sudo systemctl restart smbd;sudo systemctl restart nmbd

===== Usage on Windows =====
On Windows, each user folder can be accessed and mapped by ''\\x.x.x.x\<user>''

This way each user can have direct access to their user folder from Windows Explorer.

To access the root directory, any user can simply go to ''\\x.x.x.x'' to see the user share and view other folders.
