The procedure is as follows to add a user to samba server:

[a] First add Linux/UNIX user using useradd/adduser command.

[b] Then use same user name to add to Samba share using smbpasswd command.

NOTE: Unlike Samba 3, Samba 4 does not require a local Unix user for each Samba user that is created. Please see this note for more info.

Step # 1: Add a user joe to UNIX/Linux system

adduser command adds user to the system according to command line options and configuration information in /etc/adduser.conf. They are friendlier front ends to the low level tools like useradd.

Type any one of the following command:
# useradd joe
# passwd joe

OR
adduser joe

Step # 2: Add a user to samba

Now user joe has account on Linux/UNIX box. Use smbpasswd command to specifies that the username following should be added to the local smbpasswd file:
# smbpasswd -a joe

Step # 3: Add a user to a Samba share

By default user gets access to /home/joe from windows system. Let us say you want to give joe access to /data/accounts (make sure directory /data/accounts exists) directory. Open /etc/samba/smb.conf file and add/modify share called [accounts]:

[accounts]
comment = Accounts data directory
path = /data/accounts
valid users = vivek raj joe
public = no
writable = yes

Save the file.

Step #4: Restart the samba

# service smb restart
OR
# /etc/init.d/smb reload

A note about adding users on Samba version 4.x

Unlike Samba version 3.x and earlier, Samba version 4.x does not require a local Unix/Linux user for each Samba user that is created. The command is as follows for adding users into Samba Active Directory:
# /usr/local/samba/bin/samba-tool user add USERNAME-HERE
OR
# samba-tool user add USERNAME-HERE
Please see Samba AD DC howto for more info.

    Dear Nixcraft,
    Would you pls tell me how to do this without prompting win users for a password? I have been banging my head on wall over this Gentleman. Following is my smb.conf.
    [global]
    workgroup = MYGROUP
    server string = Samba Server Version %v
    security = share
    passdb backend = tdbsam
    load printers = yes
    cups options = raw
    [homes]
    comment = Home Directories
    browseable = no
    writable = yes
    ; valid users = %S
    ; valid users = MYDOMAIN\%S
    [printers]
    comment = All Printers
    path = /var/spool/samba
    browseable = no
    guest ok = no
    writable = no
    printable = yes

    [ux_share]
    comment = ux_share
    writable = yes
    path = /home/ux_share/share
    guest ok = yes
    browseable = yes

    I have added a user called ux_share in the system and created the /home/ux_share/share with the right permission. And created the smbuser ux_share too. Now when I try to access the share from a winbox it prompts for the passw. Please help out Nixcraft. This share is likely to access by several winusers and i have no idea about thier workgroup names whatsoever. This is just a simple share im trying to publish just like an annonymous vsftpd account.

    Regards
    V

    Samba permission problem

    /home can’t be accessed from windows client for samba.
    /tmp can be accessed but /home can’t be accessed.

    Any solution

    @yubaraj :
    1) restart winbind
    2) chmod 777 -R /home
    goodluck!
