- Select Japan at Choose country
- Select United States at Default locale
- Select American English at Keymap to use
- Select as below at Configure network
- Hostname is sambapdc
- Domain Name is sambadom.local
- Set as below at Set up users and passwords
- Set samba at Root password
- Push <Go Back> several times until Debian installer main menu is shown at Full name for new user in Set up users and passwords
- Remember that lots of unused packages are installed if you continue to install as usual
- Select as below at Partition disks
- Select Guided - use entire disk (defalt)
- Select All files in one partition (default)
- Push Finish partitioning and write changes to disk
- Select <Yes> at Write changes to disks?
- Basic packages are installed during Installing the base system Window.
- Select Install the GRUB boot loader on a hard disk
- Select <Yes> at Install the GRUB boot loader to the master boot record?
- Select <Continue> at Installation complete
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
- Adding LDAP into /etc/nsswitch.conf file

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
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
Creating home directory
# 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
- The last 7 lines before:
structuralObjectClass: olcSchemaConfig entryUUID: a671adca-3aa0-1030-8ae6-516ef773ec5f creatorsName: cn=config createTimestamp: 20110704154721Z entryCSN: 20110704154721.872107Z#000000#000#000000 modifiersName: cn=config modifyTimestamp: 20110704154721Z
- The last 7 line after:
(Removed)
- Register samba.ldif
# ldapadd -Y EXTERNAL -H ldapi:/// -f samba.ldif adding new entry "cn=samba,cn=schema,cn=config"
- Initial settings
- Create sambadom.ldif as below:
dn: olcDatabase={1}hdb,cn=config
changetype:modify
add: olcDbIndex
olcDbIndex: uidNumber,gidNumber,uid,sambaSID,cn,memberuid eq
-
add: olcAccess
olcAccess: to attrs=loginShell by dn="cn=admin,dc=samba,dc=local" write by self write by * read
olcAccess: to attrs=sambaNTPassword,sambaLMPassword,sambaPwdLastSet,sambaPwdMustChange by dn="cn=admin,dc=samba,dc=local" write by self write by * none
# ldapadd -Y EXTERNAL -H ldapi:/// -f sambadom.ldif
adding new entry "olcDatabase={1}hdb,cn=config"
Create initial schema
- Create sambadom.local.ldif file as below:
dn: ou=users,dc=sambadom,dc=local objectClass: top objectClass: organizationalUnit ou: users dn: ou=groups,dc=sambadom,dc=local objectClass: top objectClass: organizationalUnit ou: groups dn: ou=idmap,dc=sambadom,dc=local objectClass: top objectClass: organizationalUnit ou: idmap dn: ou=computers,dc=sambadom,dc=local objectClass: top objectClass: organizationalUnit ou: computers
- Register sambadom.local.ldif with ldapadd :
# cat sambadom.local.ldif | ldapadd -D cn=admin,dc=sambadom,dc=local -W -x -H ldapi:/// Enter LDAP Password: adding new entry "ou=users,dc=samba,dc=local" adding new entry "ou=groups,dc=samba,dc=local" ...
Setting Samba
- Stopping Samba
# /etc/init.d/samba stop # /etc/init.d/winbind stop
- Installing smb.conf
Create smb.conf as /etc/samba/smb.conf (included in sambapdc4.tar.gz)
# mv /etc/samba/smb.conf /etc/samba/smb.conf.org # mv smb.conf /etc/samba/smb.conf
- Installing smbusers file
Create smbusers as /etc/samba/smbusers
- Store LDAP password
# smbpasswd -w ldap Setting stored password for "cn=admin,dc=sambadom,dc=local" in secrets.tdb
- Store initial settings into LDAP
Start winbindd (only) before running 'net sam provision'
# /etc/init.d/winbind start Starting the Winbind daemon: winbind. # net sam provision Checking for Domain Users group. Adding the Domain Users group. Checking for Domain Admins group. Adding the Domain Admins group. Check for Administrator account. Adding the Administrator user. Checking for Guest user. Adding the Guest user. Checking Guest's group. Adding the Domain Guests group.
- Initial settings for Administrator user
- Setting his password 'samba'
# smbpasswd Administrator New SMB password: <== samba Retype new SMB password: <== 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
- Creating a file as /etc/rsyslog.d/samba.conf :
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
