MEMBUAT LDAP SERVER DENGAN OPEN-LDAP ( CENTOS 6.4 / RHEL 6.4 )

Biar gak lupa di tulis di blog hehe..

1) Step pertama install OPEN-LDAP-nya dengan command dibawah ini, dengan catetan udah konek ke repository lokal atau publik yah gan hehe :

[root@ldap1 ~]# yum install openldap openldap-servers openldap-clients -y

2) Copy contoh file dari konfigurasi ldapnya bernama slapd.conf ke /etc/openldap/ 

[root@ldap1 ~]# cp /usr/share/openldap-servers/slapd.conf.obsolete /etc/openldap/slapd.conf

3) Generate password untuk rootdn yg dipake oleh si /etc/openldap/slapd.conf

[root@ldap1 ~]# slappasswd
New password:
Re-enter new password:
{SSHA}GtG8bcLGeN/rf1iStKFK2pu0C2EZf/RX

4) Copy password yg sudah di generate lalu edit file /etc/openldap/slapd.conf
     note : edit yg di highlited merah

[root@ldap1 ~]# vim /etc/openldap/slapd.conf
#
# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.

# The next three lines allow use of TLS for encrypting connections using a
# dummy test certificate which you can generate by running
# /usr/libexec/openldap/generate-server-cert.sh. Your client software may balk
# at self-signed certificates, however.
#TLSCACertificatePath /etc/openldap/certs
#TLSCertificateFile "\"OpenLDAP Server\""
#TLSCertificateKeyFile /etc/openldap/certs/password

# Sample security restrictions
#       Require integrity protection (prevent hijacking)
#       Require 112-bit (3DES or better) encryption for updates
#       Require 63-bit encryption for simple bind
# security ssf=1 update_ssf=112 simple_bind=64

# Sample access control policy:
#       Root DSE: allow anyone to read it
#       Subschema (sub)entry DSE: allow anyone to read it
#       Other DSEs:
#               Allow self write access
#               Allow authenticated users read access
#               Allow anonymous users to authenticate
#       Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
#       by self write
#       by users read
#       by anonymous auth
#
# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
# updates to rootdn.  (e.g., "access to * by * read")
#
# rootdn can always read and write EVERYTHING!

# enable on-the-fly configuration (cn=config)
database config
access to *
        by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" manage
        by * none

# enable server status monitoring (cn=monitor)

access to *
        by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" read
        by dn.exact="cn=Manager,dc=example,dc=com" read
        by * none

5) Remove existing konfig LDAP sebelumnya (bila ada), lalu di re-inisialisasi :

[root@ldap1 ~]# rm -rf /var/lib/ldap/*
[root@ldap1 ~]# rm -rf /etc/openldap/slapd.d/*

6) Copy sample DB_CONFIG file ke /var/lib/ldap/
[root@ldap1 ~]# cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG

7) Set permission di /var/lib/ldap/ dan /etc/openldap/slapd.d/ ownernya jadi milik user 'ldap'

[root@ldap1 ~]# chown -Rf ldap. /etc/openldap/slapd.d/
[root@ldap1 ~]# chown -Rf ldap. /var/lib/ldap/
[root@ldap1 ~]# chmod 700 /var/lib/ldap/
[root@ldap1 ~]# chmod 700 /etc/openldap/slapd.d/

8) Cek & ricek apakah ada error di file konfigurasi /etc/openldap/slapd.conf : 
[root@ldap1 ~]# slaptest -u
config file testing succeeded

9) Convert file konfigurasi kedalam dinamik konfigurasi pada direktori /etc/openldap/slapd.d/ 
[root@ldap1 ~]# slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d
config file testing succeeded

10) Start slapd daemon untuk nyalain open-ldapnya :

[root@ldap1 ~]# /etc/init.d/slapd start

11) Confirm dengan menggunakan command dibawah ini : 

[root@ldap1 ~]# service slapd status
slapd (pid  1301) is running...[root@ldap1 ~]# netstat -ntlup | grep slapd
tcp        0      0 0.0.0.0:389                 0.0.0.0:*                   LISTEN      1301/slapd
tcp        0      0 :::389                      :::*                        LISTEN      1301/slapd

[root@ldap1 ~]# ps -ef | grep slapd
ldap      1301     1  0 08:21 ?        00:00:00 /usr/sbin/slapd -h  ldap:/// ldapi:/// -u ldap
root      1318  1208  0 08:23 pts/1    00:00:00 grep slapd

12) Apabila menggunakan iptables gunakan command dibawah ini :
[root@ldap1 ~]# netstat -ntlup | grep slapd
tcp        0      0 0.0.0.0:389                 0.0.0.0:*                   LISTEN      1402/slapd
tcp        0      0 :::389                      :::*                        LISTEN      1402/slapd

[root@ldap1 ~]# iptables -I INPUT -p udp -s 192.168.124.0/24 --dport 389 -j ACCEPT
[root@ldap1 ~]# iptables -I INPUT -p tcp -s 192.168.124.0/24 --dport 389 -j ACCEPT
[root@ldap1 ~]# iptables -I INPUT -p udp -s 192.168.124.0/24 --dport 636 -j ACCEPT
[root@ldap1 ~]# iptables -I INPUT -p tcp -s 192.168.124.0/24 --dport 636 -j ACCEPT
[root@ldap1 ~]# service iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[  OK  ]

13) Create base DIT (Directory Information Tree) file menggunakan file dibawah ini :
[root@ldap1 ~]# vim dit.ldif

#Lalu isi dengan dibawah ini :

# Creates a base for DIT
dn: dc=example,dc=com
objectClass: top
objectClass: dcObject
objectclass: organization
o: Example Organization
dc: Example
description: Example Inc DIT

# Creates a Users OU (Organizational Unit)
dn: ou=Users,dc=example,dc=com
objectClass: organizationalUnit
ou: Users

# Creates a Groups OU
dn: ou=Groups,dc=example,dc=com
objectClass: organizationalUnit
ou: Groups

dn: ou=Admins,dc=example,dc=com
objectClass: organizationalUnit
ou: Admins

# Create a user student1 with some basic info
dn: uid=student1,ou=Users,dc=example,dc=com
uid: student1
cn: student1
sn: 1
objectClass: top
objectClass: posixAccount
objectClass: inetOrgPerson
loginShell: /bin/bash
homeDirectory: /home/student1
uidNumber: 15000

gidNumber: 10000

userPassword: {SSHA}CQG5KHc6b1ii+qopaVCsNa14v9+r14r5

mail: student1@example.com

gecos: Student1 User

# Create a user student2 with some basic info
dn: uid=student2,ou=Users,dc=example,dc=com
uid: student2
cn: student2
sn: 2
objectClass: top
objectClass: posixAccount
objectClass: inetOrgPerson
loginShell: /bin/bash
homeDirectory: /home/student2
uidNumber: 15001
gidNumber: 10000
userPassword: {SSHA}CQG5KHc6b1ii+qopaVCsNa14v9+r14r5
mail: student2@example.com
gecos: Student2 User

# Creates a ldapusers group under Groups OU
dn: cn=ldapusers,ou=Groups,dc=example,dc=com
objectClass: posixGroup
objectClass: top
cn: ldapusers
userPassword: {crypt}x
gidNumber: 10000
memberuid: uid=student1
memberuid: uid=student2

14 ) Ubah file /etc/openldap/ldap.conf menjadi seperti dibawah ini :
[root@ldap1 ~]# vim /etc/openldap/ldap.conf
#
# LDAP Defaults
#
# See ldap.conf(5) for details
# This file should be world readable but not world writable.
#BASE   dc=example,dc=com
#URI    ldap://ldap.example.com ldap://ldap-master.example.com:666

#SIZELIMIT      12
#TIMELIMIT      15
#DEREF          never

#TLS_CACERTDIR  /etc/openldap/certs
ssl             start_tls
TLS_REQCERT     allow
BASE            dc=example,dc=com
URI             ldap://ldap.example.com #optional tergantung domain name anda
HOST            192.168.124.251 #optional tergantung ip address anda

15)  Execute file dit.ldif dengan command dibawah ini :
[root@ldap1 ~]# ldapadd -x -D "cn=Manager,dc=example,dc=com" -W -f dit.ldif -H ldaps://ldap1.example.com 

LDAP Password: {masukan password yg tadi dibuat dgn command slappasswd}
adding new entry "dc=example,dc=com"

adding new entry "ou=Users,dc=example,dc=com"

adding new entry "ou=Groups,dc=example,dc=com"

adding new entry "uid=student1,ou=Users,dc=example,dc=com"

adding new entry "uid=student2,ou=Users,dc=example,dc=com"

adding new entry "cn=ldapusers,ou=Groups,dc=example,dc=com"

16 ) Verivikasi data yg dimasukan dari file dit.ldif tadi sudah ada di dalem ldap databasenya dengan command dibawah ini :
[root@ldap1 ~]# ldapsearch -x -b "dc=example,dc=com" -H ldap://ldap.example.com
# extended LDIF
#
# LDAPv3
# base <dc=example,dc=com> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# example.com
dn: dc=example,dc=com
objectClass: top
objectClass: dcObject
objectClass: organization
o: Example Organization
dc: Example
description: Example Inc DIT

# Users, example.com
dn: ou=Users,dc=example,dc=com
objectClass: organizationalUnit
ou: Users

# Groups, example.com
dn: ou=Groups,dc=example,dc=com
objectClass: organizationalUnit
ou: Groups

# student1, Users, example.com
dn: uid=student1,ou=Users,dc=example,dc=com
uid: student1
cn: student1
sn: 1
objectClass: top
objectClass: posixAccount
objectClass: inetOrgPerson
loginShell: /bin/bash
homeDirectory: /home/student1
uidNumber: 14583100
gidNumber: 14564100
userPassword:: e1NTSEF9Q1FHNUtIYzZiMWlpK3FvcGFWQ3NOYTE0djkrcjE0cjU=
mail: student1@example.com
gecos: Student1 User

17) Membuat PHP-LDAP-ADMIN

Note: PHP-LDAP-ADMIN memudahkan kita dalam administrasi ldap database, menggunakan aplikasi ini kita gak perlu repot2 bikin pake dit.ldif seperti dilangkah ke 13.

*) Install phpldapadmin nya

[root@ldap1 ~]# yum install -y phpldapadmin 

*) Edit file konfigurasi httpd nya dengan menambahkan wording ini dibaris paling bawah :

[root@ldap1 ~]# vim /etc/httpd/conf/http.conf

#  Web-based tool for managing LDAP servers

#

Alias /phpldapadmin /usr/share/phpldapadmin/htdocs

Alias /ldapadmin /usr/share/phpldapadmin/htdocs

<Directory /usr/share/phpldapadmin/htdocs>

  Order Deny,Allow

  Deny from all

  Allow from all

</Directory>

*) Restart httpd server

[root@ldap1 ~]# /etc/init.d/httpd restart 

*) Buka ldap php adminnya dari web browser :

http://ldap_server_ip/ldapadmin

18) Agar bisa login dengan DN dari phpldapadmin, ubah parameter di /etc/phpldapadmin/config.php :

$servers->setValue('login','attr','uid');

menjadi 

$servers->setValue('login','attr','dn');

lalu restart lagi httpd nya :

[root@ldap1 ~]# /etc/init.d/httpd restart 

Selamat mencoba ^^
