The document provides an introduction to using Spring LDAP in J2EE applications, outlining the basics of LDAP and its integration. It includes details on managing directory entries, authentication, and CRUD operations with LDAP using Spring context configurations. Additional resources, installation steps, and examples for implementing Spring LDAP features in Java applications are also provided.

4. ECM=Enterprise Content Management
AIIM Definition (Association for Information and Image Management)
Enterprise Content Management embodies the technologies used to capture, manage, store,
preserve and deliver content and documents related to organizational processes.
Wikipedia
A system for organizing and facilitating collaborative creation of documents and other content
Able to monitor content through its lifecycle, and track changes to content, and users of
content
Sometimes a web application used for managing websites and web content
In many cases, content management systems require special client software for editing and
constructing articles

5. ECM architecture - step 1

6. ECM architecture - step 2

7. Introduction to LDAP

8. What is LDAP
Lightweight Directory Access Protocol
entries based on an hierarchical tree: Directory Information Tree (DIT)
manage information about people and services
is a protocol over TCP/IP (DAP was over OSI)
used with a Directory System Agent (DSA = LDAP Server)
Implementations
ApacheDS
OpenLDAP
OpenDS

9. LDAP stored information
Users
standard attributes (name, surname, address, age, etc...)
custom attributes (department, skills, etc...)
Groups
members
custom attributes (department, city, role)

10. LDAP data structure

11. LDAP data structure - Group

12. LDAP data structure - User

13. LDAP Directory Information Tree (DIT)

14. LDAP Directory Information Tree (DIT)

15. LDAP - BaseDN
BaseDN = ou=users, ou=system

16. LDAP - Modification Logs - add user

17. LDAP - Modification Logs - add user

18. LDAP - Modification Logs - member

19. LDAP features
Authentication ( = get LDAP context)
encrypted user passwords
LDAP connector using TCP/IP (default port 389)
Authorization ( = search attributes)
groups
members

20. Software architecture

21. Software architecture - beans graph

22. Software architecture - beans graph 2

23. Software architecture

24. Spring LDAP - resources
project page: http://www.springsource.org/ldap
downloads: http://www.springsource.com/download/community?project=Spring%20LDAP
docs: http://static.springframework.org/spring-ldap/docs/1.3.x/reference/html/
api: http://static.springframework.org/spring-ldap/docs/1.3.x/apidocs/
forum: http://forum.springframework.org/forumdisplay.php?f=40
source code: http://src.springframework.org/svn/spring-ldap/trunk

25. Spring LDAP - project page

26. Spring LDAP - how to start with Maven
add in your pom.xml the following dependencies:

27. 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 classpath
3. bind the source code for Spring LDAP libraries from:
4. spring-ldap-1.3.0.RELEASE-with-dependencies/dist/modules-source

28. The traditional way
using Java LDAP standard

29. Java LDAP

30. Spring LDAP
Spring context configuration

31. Spring Context - PropertyPlaceHolder
you can configure Spring contexts with properties files

32. Spring Context - LdapTemplate
LdapTemplate is the core of Spring LDAP

33. Spring context - ldap.properties

34. Spring LDAP
Authentication

35. Spring Context - AuthenticationDao

36. Spring Bean - AuthenticationDAO.java
IoC pattern with setter injection

37. POJO - LoginVO.java

38. LdapTemplate
Authentication using Spring LDAP 1.2.1

39. AuthenticationDAO.java - getUserDN

40. Spring Context - AuthenticationBl

41. Spring Bean - AuthenticationBl.java

42. Spring Bean - AuthenticationBl.java
how to authenticate users using Spring LDAP 1.2.1

43. LdapTemplate
Authentication using Spring LDAP 1.3.0

44. Spring Context - AuthenticationBl
add ldapTemplate to your old implementation

45. Spring Bean - AuthenticationBl.java
how to authenticate users using Spring LDAP 1.3.0
add dinamically filters for LDAP fields
authentication feature with custom constraints on your
LDAP
much easier to implement!

46. Spring LDAP
Search

47. SearchDAO.java - single attribute
returns a list with a single attribute

48. Search - PersonVO.java

49. SearchDAO.java - return an object
returns a list of Person objects

50. SearchDAO.java - find a Person

51. SearchDAO.java - dynamic filter

52. Spring LDAP
Binding - how to insert entries

53. PersonDAO.java - insert a new Person

54. Spring LDAP
Unbinding - how to remove an entry

55. PersonDAO.java - remove a Person

56. Spring LDAP
Modifying - how to change an entry

57. PersonDAO.java - Modifying using rebind
rebind = unbind + bind
very crude
maybe you don't want to do this!

58. PersonDAO.java - Modifying using modifyAttributes
