Book Description Understanding Directory Servicesclarifies the complex topic of directory services, starting with basic theory and archetypes, and then working its way up to the current directory service implementations. It describes the basic idea behind directory services, explaining the underlying conceptual models, design characteristics, and methods of managing distributed information. The book begins with an overview of directory services and their core characteristics, highlighting critical aspects of directory information, distribution, and storage. The evolving nature of the information the directory contains, and the factors involved in organizing and managing it are discussed in detail, and then methods of information distribution and storage are examined at length. After exploring the basics of directory service, the book progresses to in-depth chapters on each of the critical technologies being used to implement directory services: * The X.500standards are explained to help you understand the foundations of directory services and provide a basis for comparison of the other directory technologies. *Lightweight Directory Access Protocol(LDAP) and its emerging role as a directory access standard is described in detail, with thorough explanations of models, naming, and operations. *The Domain Name System(DNS) is examined from a directory service perspective, noting parallels in structures and operations. This knowledge of directory services is then used to describe the design of X.500 and LDAP based directory service products, as well as NDS eDirectory and Active Directory, highlighting the architectural and operational implications of vendor's design decisions. This book: * Explores X.500-based directory products (eTrust, DirX, Nexor), and highlights implementation approaches and capabilities. * Describes the LDAP-based directory products (OpenLDAP, SecureWay, iPlanet), identifying similarities and differences between them. * ExplainsNDS eDirectorydescribing the underlying directory architecture and its foundations in X.500, and its evolution from an NOS-based directory to a general purpose directory service. * Examines howActive Directoryintegrates NT 4, LDAP, and DNS technologies into a directory service that leverages established Windows networks. * Explores the information management issues that meta-directories (Siemens DirXmetahub, iPlanet meta-directory, Microsoft Meta-directory Services, Novell DirXML) are designed to address, and characteristics of different types of meta-directory solutions (as well as Radiant Logic'sRadiant Onevirtual directory server). * Identifies the design of XML-based directory markup languages that map directory schema, objects, and operations providing directory interoperability. The final chapter is focused on helping you evaluate directory services in the context of your business and network environment. Information, business, and network control factors are identified, and key factors in directory service assessment are explained. Understanding Directory Servicesis an excellent reference for directory service technologies that includes extensive references and aglossarycontaining 385 directory service terms. By explaining key directory technologies, and the integration of those technologies, this book provides the information you need to understand the design and operations involved in all directory services. From the Back Cover Understanding Directory Servicesis the most in-depth resource available on directory services theory, architecture, and design. It provides the conceptual framework and critical technical information for IT professionals who are using directory services in their networks or e-business solutions. The 1st edition of this book covered the underlying directory service technologies (X.500, LDAP, DNS), and integrated the information from a networking perspective with a special focus on eDirectory and Active Directory. The 2nd Edition extends this coverage to the LDAP-based directories (such as iPlanet and SecureWay) and the X.500-based enterprise directory services (including eTrust, DirX, and Nexor), as well as the emerging meta-directory technologies and products which are crucial to the integration of the multiple directories in an enterprise networking environment. By explaining the origins and technologies of directory services, and clarifying the integration of key directory technologies into network and e-commerce platforms,Understanding Directory Servicesgives you the information you need to understand the underlying design and operations involved in all directory services.

Charles Edge and Bill Smith provide detailed explanations of the technology required for large-scale Mac OS X deployments and show you how to integrate it with other operating systems and applications. Now in its second edition, Enterprise Mac Administrator's Guide addresses the growing size and spread of Mac OS X deployments in corporations and institutions worldwide. In some cases, this is due to the growth of traditional Mac environments, but for the most part it has to do with organizations instituting device choice and switcher campaigns, where Windows and/or Linux environments are migrating to Mac OS X. There is a steep culture shock with many of these migrations. The products that are used are different, the nomenclature is different, and most importantly the best practices for dealing with the operating system and updates are very different. Apple provides a number of tools to help automate and guide IT toward managing a large number of Mac OS X computers—it has since before Mac OS X was initially released. However, if you want to put together all of the pieces to tell a compelling story about how to run an IT department or a deployment of Macs, you need to compile information from a number of different sources. This book provides explanations of the technology required. What You'll Learn Choose a directory services model that works for your organization and integrate it into your existing model Choose an imaging model and begin imaging workstations with or without third-party products Use the Mac App Store and Apple’s Volume Purchasing Program to deploy apps Leverage scripting techniques to reduce labor for the IT department Provide network services (file sharing, mobile home folders, messaging, etc.) to the Mac OS X clients Who This Book Is For System administrators and IT professionals who need to manage a large number of Mac OS X computers, be they Mac OS X–based servers or workstations. The assumption is that readers are somewhat familiar with Mac OS X and/or IT in general, but not that they are familiar with the Apple system internals, server services, or deployment techniques.

Both authors have taught the course of “Distributed Systems” for many years in the respective schools. During the teaching, we feel strongly that “Distributed systems” have evolved from traditional “LAN” based distributed systems towards “Internet based” systems. Although there exist many excellent textbooks on this topic, because of the fast development of distributed systems and network programming/protocols, we have difficulty in finding an appropriate textbook for the course of “distributed systems” with orientation to the requirement of the undergraduate level study for today’s distributed technology. Specifically, from - to-date concepts, algorithms, and models to implementations for both distributed system designs and application programming. Thus the philosophy behind this book is to integrate the concepts, algorithm designs and implementations of distributed systems based on network programming. After using several materials of other textbooks and research books, we found that many texts treat the distributed systems with separation of concepts, algorithm design and network programming and it is very difficult for students to map the concepts of distributed systems to the algorithm design, prototyping and implementations. This book intends to enable readers, especially postgraduates and senior undergraduate level, to study up-to-date concepts, algorithms and network programming skills for building modern distributed systems. It enables students not only to master the concepts of distributed network system but also to readily use the material introduced into implementation practices.
