SAMBA (Domaincontroller) Server For Small Workgroups With Ubuntu 7.10

SAMBA Server

apt-get install libcupsys2 samba samba-common samba-doc smbclient winbind cupsys-common

Edit /etc/samba/smb.conf that it looks like this:

vi /etc/samba/smb.conf

workgroup = MYWORKGROUP
netbios name = SERVER1
server string = %h server (Samba, Ubuntu)

passdb backend = tdbsam
security = user
username map = /etc/samba/smbusers
name resolve order = wins bcast hosts
domain logons = yes
preferred master = yes
wins support = yes

# Set CUPS for printing
load printers = yes
printcap name = CUPS
printing = CUPS

# Default logon
logon drive = H:
logon script = scripts/logon.bat
logon path = \\server1\profile\%U

# Useradd scripts
# add user script = /usr/sbin/adduser –quiet –disabled-password –gecos “” %u
add user script = /usr/sbin/useradd -m ‘%u’ -g users -G users
delete user script = /usr/sbin/userdel -r %u
add group script = /usr/sbin/groupadd %g
delete group script = /usr/sbin/groupdel %g
add user to group script = /usr/sbin/usernod -G %g %u
add machine script = /usr/sbin/useradd -s /bin/false/ -d /var/lib/nobody %u
idmap uid = 15000-20000
idmap gid = 15000-20000
template shell = /bin/bash

# sync smb passwords woth linux passwords
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* .
passwd chat debug = yes
unix password sync = yes

# set the loglevel
log level = 3

browseable = yes
public = yes

comment = Home
valid users = %S
read only = no
browsable = no

comment = All Printers
path = /var/spool/samba
printable = yes
public = no
writable = no
create mode = 0700

comment = Printer Drivers
path = /var/lib/samba/printers
browseable = yes
read only = yes
guest ok = no
write list = root, @smbadmin

comment = Network Logon Service
path = /home/samba/netlogon
admin users = Administrator
valid users = %U
read only = no
guest ok = yes
writable = no
share modes = no

comment = User profiles
path = /home/samba/profiles
valid users = %U
create mode = 0600
directory mode = 0700
writable = yes
browsable = no
guest ok = no

Create the directories for domain logons and profiles:

mkdir /home/samba
mkdir /home/samba/netlogon
mkdir /home/samba/profiles
chmod 777 /var/spool/samba/
chown -R root:users /home/samba/
chmod -R 771 /home/samba/

Now we restart Samba:

/etc/init.d/samba restart

Edit /etc/nsswitch.conf. Change the line:

vi /etc/nsswitch.conf

hosts: files dns


hosts: files wins dns

Add all computers of your workgroup in the /etc/hosts file on the server.

vi /etc/hosts server1 workstation1 workstation2 workstation3 workstation4

Add the root user to the SAMBA password database. The root user (alias: Administrator) will be our domain Administrator. This account is needed to add new computers to the SAMBA domain.

smbpasswd -a root

Create the file /etc/samba/smbusersand add the line by executing:

echo “root = Administrator” > /etc/samba/smbusers

This will allow us to use the common Windows username “Administrator” as an alias for the Linux root user.

Now I will test if the setup is correct:

smbclient -L localhost -U%

The output shall look similar to this:

Domain=[MYWORKGROUP] OS=[Unix] Server=[Samba 3.0.26a]

Sharename       Type      Comment
———       —-      ——-
IPC$            IPC       IPC Service (samba server (Samba, Ubuntu))
netlogon        Disk      Network Logon Service
print$          Disk      Printer Drivers
Domain=[MYWORKGROUP] OS=[Unix] Server=[Samba 3.0.26a]

Server               Comment
———            ——-
SERVER1              samba server (Samba, Ubuntu)

Workgroup            Master
———            ——-

Set up the default domain groups for windows:

net groupmap add ntgroup=”Domain Admins” unixgroup=”root” type=domain -U root
net groupmap add ntgroup=”Domain Users” unixgroup=”users” type=domain -U root
net groupmap add ntgroup=”Domain Guests” unixgroup=”nogroup” type=domain -U root
Adding Users To Our SAMBA Domain

Now we will add a user, e.g.”tom”, to our Samba domain. You will have to add a user like this for each user account you want to connect to this SAMBA domain server.

Add the user “tom” with password “secret” to the Samba and Linux user database:

net rpc user add tom -U root
net rpc user password tom “secret” -U root
smbpasswd -e tom
Adding Shares

Now I will add a share that is accessible by all users:

mkdir -p /home/shares/allusers
chown -R root:users /home/shares/allusers/
chmod -R ug+rwx,o+rx-w /home/shares/allusers/

At the end of the file /etc/samba/smb.conf add the following lines:

comment = All Users
path = /home/shares/allusers
valid users = @users
force group = users
create mask = 0660
directory mask = 0771
writable = yes

Now we restart Samba:

/etc/init.d/samba restart
