document, the Kopano Core Administrator Manual, describes how to install, upgrade, configure and maintain KC on your system. In addition various advanced configurations and integration options are covered. Contents 1 CHAPTER 1 Abstract Kopano Core provides the core MAPI-enabled messaging stack with the stability and flexibility of the linux platform. Kopano Core acts as the solid foundation for groupware messaging based on MAPI and enabling rich web clients such as Kopano WebApp or Kopano DeskApp as well as mobile and sync clients. With the modular architecture, Kopano Core hereby allows a variety of setup scenarios, scalable from a very low powered system to a multi-datacenter setup providing messaging capabilities to tens of thousands of users. Kopano Core is entirely open source, licensed under the GNU Affero General Public License version 3, and can be downloaded from Kopano’s download servers. Kopano Core is provided in two ways: • Repositories, available to customers with a valid Kopano subscription. • Downloadable & installable packages for community usage. 2 CHAPTER 2 Introduction Kopano Groupware Core (KGC) is an open source software suite capable of providing a complete MAPI-based groupware stack with extensive interfacing capabilities. It’s architecture is very modular, makes use of standards wherever possible, and integrates with common open source components. This document explains how to perform the most common administrative tasks with KGC. Important: Although we, Kopano, try our best to keep the information in this manual as accurate as possible, we reserve the right to modify this information at any time, without prior notice. 2.1 Intended Audience This manual is intended for system administrators responsible for installing, maintaining, and supporting the KGC deployment. We assume readers of this manual will a thorough understanding of: • Linux system administration concepts and tasks • Email communication standards • Security concepts • Directory services • Database management 2.2 Architecture In accord with the UNIX philosophy, KGC consists of components that each take care of a well defined task. See the KGC Architecture Diagram which describes the relationships between the components and the protocols used. This diagram describes a simple setup as used by most of our customers. Only the most commonly used components are shown in the diagram. The top part of the diagram shows the clients: software appliances by which users access their data. Some of these appliances are desktop applications, some are mobile applications. 3 KC Administrator Manual, Release 8.0.0 In between “The Internet” and the “Kopano Server”, the infrastructure components of Kopano (blue) and some common infrastructure components (grey) can be found.

  • Samba-3 by Example
    Samba-3 by Example Practical Exercises in Successful Samba Deployment John H. Terpstra May 27, 2009 ABOUT THE COVER ARTWORK The cover artwork of this book continues the freedom theme of the first edition of \Samba-3 by Example". The history of civilization demonstrates the fragile nature of freedom. It can be lost in a moment, and once lost, the cost of recovering liberty can be incredible. The last edition cover featured Alfred the Great who liberated England from the constant assault of Vikings and Norsemen. Events in England that finally liberated the common people came about in small steps, but the result should not be under-estimated. Today, as always, freedom and liberty are seldom appreciated until they are lost. If we can not quantify what is the value of freedom, we shall be little motivated to protect it. Samba-3 by Example Cover Artwork: The British houses of parliament are a symbol of the Westminster system of government. This form of government permits the people to govern themselves at the lowest level, yet it provides for courts of appeal that are designed to protect freedom and to hold back all forces of tyranny. The clock is a pertinent symbol of the importance of time and place. The information technology industry is being challenged by the imposition of new laws, hostile litigation, and the imposition of significant constraint of practice that threatens to remove the freedom to develop and deploy open source software solutions. Samba is a software solution that epitomizes freedom of choice in network interoperability for Microsoft Windows clients.

  • Getting Ready for Samba4
    Getting Ready for Samba4 Samba Team member Andrew Bartlett explores the world of Samba4, its development status, what you can (and can’t) do with Samba4, and — most importantly– when you can expect to start using Samba4 in a production environment. Andrew Bartlett Thursday, April 3rd, 2008 Ever wanted to run an Active Directory Domain Controller on your Linux server? Did you run a Samba 3.0 DC, but had to move to Active Directory, or worried you might need to? Interested in the leading edge of Samba development, and wondering what the preceding questions mean? Without Samba, Linux, Windows and Macintosh computers could not share files and printers with each other, and networks of windows computers could only use Microsoft’s products to implement consistent user names and passwords across an organisation, something known as domain control. Since Samba was last covered by Linux Magazine in 2002, it seems the whole world has changed. Yet for members of the Samba Team the task remains to provide the Free Software community with a solid implementation of the Common Internet File System (CIFS) protocol, and with that a bridge into the Windows world. It is in that pursuit of interoperability that the Samba Team has continued, soon (at the time of writing) releasing version 3.2.0 of Samba, and alpha releases of Samba4. But Samba4 is more than just a new version of Samba, and more akin to a new development effort. Largely rewritten to handle the problems of interacting with modern versions of Microsoft’s Windows suite, Samba4 has been a storehouse of testing and innovation.
