ABSTRACT
The Lightweight Directory Access Protocol (LDAP) protocol runs over Transmission Control Protocol/Internet Protocol, and the command-line tools are no more than small client applications. Of course, the client application has to be installed on system, and it is the client application that imposes the syntax of the commands entered by the user. The client application then speaks with the directory server using the standard LDAP protocol. The chapter anlalyses many aspects of LDAP without going into the details. It introduces some key concepts and presents examples of LDAP at work so that the reader could begin using basic LDAP commands. The best way to learn how to use new software is to install it and then play around with it. The directory server will refuse the name change because the “HR” entry has subentries. The “HR” organizational unit has sibling entries of the objectClass “person.”
