Basic LDAP Training

Duration: 2 or 3 days. If three days the last day is the Advanced LDAP Course.

La formation est aussi disponible en français.

The course uses OpenLDAP which is available on Linux, UNIX and Windows platforms to illustrate LDAP principles and operation and which is relatively invisible during the basic course. The course makes extensive use of a platform independent LDAP browser to discover and interrogate LDAP implementations including Windows Active Directory. The course is offered with Linux (Fedora Core), FreeBSD or Windows as the platform for all exercises.

Introduction

Lightweight Directory Access Protocol (LDAP) is re-emerging as the standard for managing resources and objects used within and in some cases between organizations. The hierarchical, yet flexible architecture, of LDAP makes it suitable for a wide range of tasks from simple customer address lists through operational provision of Single Sign-On (SSO and Identity Management) to a repository for network wide policy management. With resilience, platform independence and distributed functionality built-in, coupled with LDAP abstraction layers available from most transaction oriented database suppliers, LDAP is the ideal standards based approach to unifying data usage on an enterprise wide basis. Microsoft's Active Directory is but one of a number of enterprise wide solutions using LDAP to glue together disparate data.

Description

Students will learn the theory and organization of the LDAP hierarchy or Object Tree Structure covering the Data Information Tree (DIT), objectClasses and attributes. LDAP Interchange Files (LDIF), LDAP security, STRUCTURAL, AUXILIARY and ABSTRACT Object Classes, Schemas, ASN.1 notation, matching rules, indexing and searching are all covered in detail. Students will construct a simple application when the basic theory has been covered and then progressively enhance the application with increasingly complex functionality to both fully illustrate all the architectural elements and as a practical demonstration of the flexibility and extensibility of LDAP. A platform independent LDAP browser is used throughout the course to examine both the students application and the Windows Active Directory LDAP implementation.

Audience:

The course is optimized for LDAP designers, architects and implementors, Network and System administrators and those who need a thorough understanding of LDAP technology.
