Introduction to LDAP

What is LDAP

Lightweight Directory Access Protocolentries based on an hierarchical tree: Directory Information Tree (DIT) manage information about people and servicesis a protocol over TCP/IP (DAP was over OSI)used with a Directory System Agent (DSA = LDAP Server)

Implementations

ApacheDSOpenLDAPOpenDS

LDAP stored information

Usersstandard attributes (name, surname, address, age, etc...) custom attributes (department, skills, etc...)

Groups

memberscustom attributes (department, city, role)

LDAP data structure

LDAP data structure - Group

LDAP data structure - User

LDAP Directory Information Tree (DIT)

LDAP - BaseDN

BaseDN = ou=users, ou=system

LDAP - Modification Logs - add user

LDAP features

Authentication ( = get LDAP context)encrypted user passwordsLDAP connector using TCP/IP (default port 389)

Authorization ( = search attributes)

Spring LDAP - how to start with Maven

add in your pom.xml the following dependencies:

Spring LDAP - how to start without Maven

1. download the latest stable with dependecies from here: http://www.springsource.com/download/community?project=Spring%20LDAP

2. extract and import all the libraries in your classpath3. bind the source code for Spring LDAP libraries from: 4. spring-ldap-1.3.0.RELEASE-with-dependencies/dist/modules-source

The traditional way

using Java LDAP standard

Java LDAP

Spring LDAP

Spring context configuration

Spring Context - PropertyPlaceHolder

you can configure Spring contexts with properties files

Spring Context - LdapTemplate

LdapTemplate is the core of Spring LDAP

Spring context - ldap.properties

Spring LDAP

Authentication

Spring Context - AuthenticationDao

Spring Bean - AuthenticationDAO.java

IoC pattern with setter injection

POJO - LoginVO.java

LdapTemplate

Authentication using Spring LDAP 1.2.1

AuthenticationDAO.java - getUserDN

how to authenticate users using Spring LDAP 1.2.1

Spring Context - AuthenticationBl

Spring Bean - AuthenticationBl.java

Spring Bean - AuthenticationBl.javahow to authenticate users using Spring LDAP 1.2.1

LdapTemplate

Authentication using Spring LDAP 1.3.0

Spring Context - AuthenticationBl

add ldapTemplate to your old implementation

Spring Bean - AuthenticationBl.java

how to authenticate users using Spring LDAP 1.3.0

add dinamically filters for LDAP fieldsauthentication feature with custom constraints on your LDAPmuch easier to implement!

Spring LDAP

Search

SearchDAO.java - single attribute

returns a list with a single attribute

Search - PersonVO.java

SearchDAO.java - return an object

returns a list of Person objects

SearchDAO.java - find a Person

SearchDAO.java - dynamic filter

Spring LDAP

Binding - how to insert entries

PersonDAO.java - insert a new Person

Spring LDAP

Unbinding - how to remove an entry

PersonDAO.java - remove a Person

Spring LDAP

Modifying - how to change an entry

PersonDAO.java - Modifying using rebind

rebind = unbind + bindvery crude maybe you don't want to do this!

PersonDAO.java - Modifying using modifyAttributes
