Basic settings

Added settings for eth1 if needed

Added these settings in /etc/network/interfaces

allow-hotplug eth1
iface eth1 inet dhcp

Configure APT

Modify /etc/apt/sources.list

deb http://ftp.jp.debian.org/debian etch main
deb http://security.debian.org/ etch/updates main

Note that only main is set because of reducing disk space.

Specify tmpfs for filesystem of /tmp

add /etc/fstab as below:

/dev/shm   /tmp   tmpfs defaults 0 0

This is not necessary but reduces disk space for install

Specify tmpfs for /var/cache/apt

add /etc/fstab as below:

/dev/shm   /var/cache/apt   tmpfs defaults 0 0

This is not necessary but reduces disk space for install

Enable these changes

# mount /tmp
# mount /var/cache/apt

Installing ftp

Uses only to receive files

# apt-get install ftp
# apt-get clean

Installing packages for ACL and extended attributes

# apt-get install attr acl

Add acl,user_xattr as mount option in /etc/fstab

change errors=remount-ro to defaults,acl,user_xattr,errors=remount-ro

change mount options with remount option

mount -o remount,rw,acl,user_xattr,errors=remoun-ro /dev/sda1 /

Build Samba + LDAP environment

Installing and setting packages

Install and Configuring libnss-ldap and libpam-ldap

apt-get install libnss-ldap libpam-ldap

Setting of libnss-ldap

URL is ldapi:///

DN is dc=sambadom,dc=local

LDAP version is 3

LDAP account for root is cn=admin,dc=sambadom,dc=local

Password is ldap

Settings of libpam-ldap

Allow LDAP admin account ... is <Yes>

Does the LDAP database require login? is <No>

LDAP account for root is cn=admin,dc=sambadom,dc=local

Password is ldap

Installing Samba and OpenLDAP

installing slapd package

# apt-get install slapd ldap-utils

Set ldap as Admin password

ldap-utils package is for management purpose, so it is not required for running, although the description is assumed it is installed.

Installing Samba packages

# apt-get install samba winbind smbclient

Set SAMBADOM as workgroup/domain name

smbclient package is for management and test purpose, so it is not required for running.

Installing pam_smbpass package

# apt-get install libpam-smbpass

Removing nscd

Running nscd sometime makes a trouble that adding or removing an user or a group is not affected immediately.

# apt-get remove nscd

PAM configuration

Because pam-auth-update command automatically sets PAM related-files, basically we do not need to edit them manually.

But we have to set these settings manually:

/etc/pam.d/common-password

Comment out pam_winbind.so line.

/etc/pam.d/common-session

Add mkhomedir option in pam_winbind.so line.

Installing crackcheck command

Installing cracklib package

apt-get install libcrack2

used by crackcheck command

Run on the box where development packages are installed.

# apt-get install cracklib2-dev

# apt-get install samba-doc
# cd /usr/share/doc/samba-doc/examples/auth/crackcheck
# make
# strip crackcheck

Copy crackcheck binary to /usr/local/sbin/crackcheck on sambapdc

Installing mgrshare script

Extract mgrshare script (included in [http://wiki.samba.gr.jp/mediawiki/images/1/10/Sambapdc4.tar.gz sambapdc4.tar.gz] ) and install:

# mv mgrshare  /usr/local/sbin/mgrshare
# chmod +x /usr/local/sbin/mgrshare

Installing smbchsh

Extract smbchsh script (included in [http://wiki.samba.gr.jp/mediawiki/images/1/10/Sambapdc4.tar.gz sambapdc4.tar.gz] ) and install to /usr/local/bin/smbchsh.

Here is the content of smbchsh:

#!/bin/sh

SHELL=$1

echo "dn: uid=${USER},ou=users,dc=samba,dc=local
changetype: modify
replace: loginShell
loginShell: $1
" | ldapmodify -x -D "uid=${USER},ou=users,dc=samba,dc=local" -W

Installing remove-old-files-in-recycle-bin

Extract remove-old-files-in-recycle-bin script (included in [http://wiki.samba.gr.jp/mediawiki/images/1/10/Sambapdc4.tar.gz sambapdc4.tar.gz] ) and install as /usr/local/sbin/remove-old-files-in-recycle-bin:

#!/bin/sh

trashdir=.recycle
rootdir=/var/lib/samba/shares
olddays=14

cd ${rootdir}

for targetdir in *; do
  if [ -d ${targetdir}/${trashdir} ]; then
    cd ${targetdir}/${trashdir}
    find . -atime +${olddays} -exec rm {} \;
  fi
done

# mkdir /home/SAMBADOM

Creating smbusers file

Extract smbusers file (included in [http://wiki.samba.gr.jp/mediawiki/images/1/10/Sambapdc4.tar.gz Sambapdc4.tar.gz] ) and install as /etc/samba/smbusers

Setting Samba + LDAP environment

Setting LDAP

Remember that LDAP settings are stored in LDAP after Squeeze

Installing schema file for Samba

# apt-get install samba-doc
# apt-get clean

# zcat /usr/share/doc/samba-doc/examples/LDAP/samba.schema.gz > /etc/ldap/schema/samba.schema

# apt-get remove samba-doc
# apt-get clean

samba-doc package is removed after extracting schema file

Generating LDIF file for Samba schema

# cd /tmp
# ln -s /etc/ldap/schema .
# mkdir dummy_slapd.d

Creating /tmp/dummy_slapd.conf file as below:

include schema/core.schema
include schema/cosine.schema
include schema/inetorgperson.schema
include schema/nis.schema
include schema/samba.schema

# slaptest -f dummy_slapd.conf -F dummy_slapd.d
config file testing succeeded

Modifying LDIF file

Rename cn={4}samba.ldif under dummy_slapd.d/cn=config/cn=schema to samba.ldif

and modify as below:

- The top 3 lines before:

dn: cn={4}samba
objectClass: olcSchemaConfig
cn: {4}samba

- The top 3 lines after:

dn: cn=samba,cn=schema,cn=config objectClass: olcSchemaConfig cn: samba

Starting Samba

Setting automated home directory creation

Create a file as /usr/local/sbin/createhomedir and chmod +rx :

This setting is needed because automated home directory creation via PAM cannot work with Samba.

#!/bin/bash

homedir=/home/$1/$2

if [ ! -d $homedir ]; then
        mkdir $homedir
        chmod 700 $homedir
        chown $2:domusers $homedir
fi
exit 0

Setting syslog

local1.*                -/var/log/samba/log.audit

And

# touch /var/log/samba/log.audit
# /etc/init.d/rsyslog restart

Creating a file as /etc/logrotate.d/samba-syslog :

/var/log/samba/log.audit
{
       rotate 4
       weekly
       missingok
       notifempty
       compress
       delaycompress
