For companies struggling to integrate information stored in multiple overlapping directories, LDAP and Microsoft"s Active Directory Services Interfaces (ADSI) offer a powerful solution. Now, there"s a complete, practical guide to building LDAP and ADSI applications using Microsoft"s latest technologies. The book starts by reviewing the fundamental concepts underlying LDAP; then introduces the basic LDAP programming model, Microsoft"s LDAP implementation for Microsoft Exchange 5.x, and how native LDAP maps to ADSI objects. With this foundation in place, the book walks through construction of two sample applications, first using LDAP and then ADSI, so developers can evaluate the key similarities and differences between each approach. The programming examples become increasingly complex, culminating in the construction of a general-purpose Active Directory browser. For all directory services application developers, especially those working with LDAP, Active Directory, ADSI, Microsoft Exchange, and/or Windows 2000/NT Server.
