LDAP

Нужна минимальная инсталляция LDAP для интеграции CD/CD инструментов - gerrit и jenkins

• Коротко о том что такое DN, CN ... http://wiki.sirmax.noname.com.ua/index.php/LDAP_general_info

Assumptions

• Server IP: 192.168.56.102
• Server Name: cicd
• Root DN: demo
• Any password (for all users): r00tme
• OS: Ubunti 14.04

Подготовка

• add key

mkdir -p /root/.ssh
/root/.ssh/authorized_keys

Установка пакетов:

sudo apt-get update
sudo apt-get install slapd ldap-utils phpldapadmin mc vim strace tcpdump tcpflow 

После установки

Check for running processes:

ps -auxfw

Настройка

dpkg-reconfigure slapd

Configure Password: r00tme

Configure root DN: demo for this demo.

Check configuration

2 steps to check configuration:

• chack with slapcat which shows data directly from files even if OpenLDAP server process is not running.
• Check with ldapsearch, which operate as ldap client.

slapcat

slapcat

Result:

dn: dc=demo
objectClass: top
objectClass: dcObject
objectClass: organization
o: demo
dc: demo
structuralObjectClass: organization
entryUUID: 2dd35bc8-85f2-1035-8d51-1b798eec3e6d
creatorsName: cn=admin,dc=demo
createTimestamp: 20160324095443Z

modifiersName: cn=admin,dc=demo
modifyTimestamp: 20160324095443Z

As you can see we have

• dn: dc=demo (root object)
• dn: cn=admin,dc=demo (admin user)

ldapsearch

Check admin passwod (connection to LDAP with ldapsearch):

• user: cn=admin,dc=demo
• search base (:where to search from") dc=demo

ldapsearch -D "cn=admin,dc=demo" -w r00tme -b "dc=demo"

Result:

dn: dc=demo
objectClass: top
objectClass: dcObject
objectClass: organization
o: demo
dc: demo

# admin, demo
dn: cn=admin,dc=demo
objectClass: simpleSecurityObject
objectClass: organizationalRole
cn: admin
description: LDAP administrator
userPassword:: e1NTSEF9akxUN0FaVGN2OGg4d0FPcHNQWHJPWG8wL3VleXJIaWs=

search: 2
result: 0 Success

So now we have OpenLDAP server with

PHP LdapAdmin

Configuration

In file /etc/phpldapadmin/config.php change 2 lines:

$servers->setValue('server','base',array('dc=demo'));
$servers->setValue('login','bind_id','cn=admin,dc=demo');

This changes are configured phpldapadmin to use correct root dn and default user.

Check

• Open in browser http://192.168.56.102/phpldapadmin/

Log-in with credentials

• Login name: cn=amin, dc=demo
• Password: r00tme

See LDAP tree with 2 objects:

• root dc=demo
• admin user
