LDAP, the Lightweight Directory Access Protocol, is a set of Internet standards for communications and operations with and between directory servers. Directory servers play a key role in modern Information Technology infrastructures, being the repositories of choice for the identity management systems used to authenticate and authorize user access to enterprise applications. OpenLDAP is an open source implementation of a general purpose directory server that is both high performance and LDAP standards compliant.The goal of this book is to prepare a system administrator or software developer for building a directory using OpenLDAP, and then employing this directory in the context of the network. To that end, this book will take a practical approach, emphasizing how to get things done. On occasion, we will delve into theoretical aspects of LDAP, but such discussions will only occur where understanding the theory helps us answer practical questions.
