Simple Samba Setup

Simple Samba (SMB) Setup with the focus of having a file share method for www developers on windos machines.

Install Samba on Debian or Ubuntu

apt-get install samba samba-common system-config-samba

Configure Samba with a local user for www-data

Configure Samba with a local user to authenticate and enforce the user www-data to be used on the share level

• Add a new group

addgroup sambagrp

• Create a user (demo01), no home directory and no local login, just to authenticate with Samba, add the user to the new group

useradd demo01 -M -G sambagrp -s /usr/sbin/nologin 

• Add a the new user (-a) to the Samba authentication and create a new password

smbpasswd -a demo01

• Create or edit /etc/samba/smb.conf

[global]
   workgroup = WORKGROUP
   server string = %h server (Linux)
   interfaces = eth0
   bind interfaces only = yes
   log file = /var/log/samba/log.%m
   panic action = /usr/share/samba/panic-action %d
   server role = standalone server
   obey pam restrictions = Yes
   passwd program = /usr/bin/passwd %u
   passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
   pam password change = Yes
   map to guest = Bad User
   #log level = 4 #To be used for debugging purposes

[www]
   comment = www
   path = /var/www
   valid users = @sambagrp
   browsable = yes
   writable = yes
   read only = no
   force user = www-data

• Restart Samba

systemctl restart smbd

Ready to use the demo01 user to connect to the Samba Server

Configure Samba with a foreign user for www-data

Configure a new user which gets authenticated with other methods such as 'sssd (ldap authentication)' like with ActiveDirectory

addgroup ldapgrp

usermod -a -G ldapgrp  <ldap user>
