Foreword
Shared, networked file and print services are the heart and blood of any office
environment. They allow users of a network to store their files reliably, share them
with each other, and bridge the gap between multiple places of work, multiple
devices and tools, and multiple operating systems.
The latter aspect is key to a modern work environment: integrating the worlds of
Unix/Linux and Mac OS X with the traditional Windows PC environment not only
allows users of a "foreign" OS to collaborate in a Windows-dominated world, it also
enables Windows environments to benefit from the power of Unix/Linux server
environments with advanced networking, high availability, backup/recovery, and
automation capabilities as well as integration with enterprise-class infrastructure
and tools.
When Andrew Tridgell implemented the first version of Samba in 1991, he probably
did not foresee the tremendous impact that his software would have on today's
office productivity environments and the role it would fill as the bridge between
two worlds that couldn't be more different from each other. Yet, this is exactly what
makes Samba so fascinating: the power to integrate the Windows world with the
Unix/Linux/Mac OS X world, the Rosetta Stone of filesystem protocols.
Wielding this power can be difficult and complicated. In today's hectic world of
IT system administration, the pressure to deliver a robust, stable, highly available,
and dependable infrastructure at a low cost has never been greater. Modern system
administrators frequently don't have the time or training to understand every
possible aspect of any given software, especially if it is a complex system that has
grown over several decades. They need simple, practical, relevant advice on how to
accomplish their day-to-day tasks, enabling them to get the basics of file and print
services up and running. They need to do so quickly and efficiently, so they can
concentrate on higher-level tasks, knowing that the key underlying infrastructure is
in place and running reliably.

I'm very happy to see that Marcelo has accepted the challenge of boiling down heaps
of documentation, white papers, and other collateral into a single, concise, practical
guide to implementing Samba 4. Marcelo draws from over a decade of experience in
running large-scale IT projects, from high-level planning to the nitty-gritty details of
command-line options and complex troubleshooting.
And the result is a clear, concise, extremely useful step-by-step guide on how to set
up your Samba 4 environment: from basic installation to AD Domain Controller
setup and management, migration from an existing Windows server environment,
upgrading from Samba 3, running file and print services, LDAP, clustering, and of
course scripting. This guide has got you covered.
Of course, no guide can replace the full documentation or address the intricacies
of every single corner case. But staying true to the Pareto principle, this is exactly
the 20 percent of documentation that you need to read to get 80 percent of your
Samba 4 work done. With Marcelo's expertise boiled down into a single book, you
can get up and running quickly, then concentrate your energy into those aspects
of your installation that are unique to your environment and that warrant your
special attention.
IT system administrators often have an aura of "IT wizards" around them, as if they
had the power to "heal" a broken computer with the touch of a hand. This "magic"
really stems from decades of experience; hard-learned intuition; and the tedious,
day-to-day work of getting IT stuff done. I hope that the "virtual Marcelo" distilled into
this book can help you become such a "Samba wizard", enabling you to ensure that
your organization's productivity is covered, at least from a file and print perspective.

About the Author
Marcelo Leal studied at Unisinos, where he undertook a Bachelor's degree in
Computing Science. Having worked in the IT industry for more than 15 years, he
has gained experience as a network/system administrator, support manager, Unix/
Linux specialist, storage architect, and most recently, as a solutions architect. He was
involved in open source projects since the beginning of his career and has developed
some open source tools and submitted patches to the GNU/Linux and FreeBSD
kernel. In 2005, he was honored for his participation in the Prêmio TI e Governo for
the project "Metrópole", Porto Alegre/RS. He was one of the founders of the Porto
Alegre OpenSolaris User Group (PoaOSUG) and was a contributor for the Open
High Availability Cluster Community (OHAC) within the OpenSolaris Project; he
was the first person outside Sun Microsystems to contribute code to the Open Cluster
software. He received three prizes at the OpenSolaris innovation awards program
(2007-2008), and presented a solution for Storage High Availability using nonshared
disks at the first OHAC Summit in San Francisco/California, USA (2009). In 2013,
he presented a highly available, scalable, and high performance three-layer storage
solution at SNIA SpeedConf, Santa Clara/California, USA, which, besides adding
a lot of value to the storage service, provided huge savings in capex and opex costs
(millions of dollars in three years). He has led the architecture and development of
a distributed Storage Appliance that, in three years, provided more than 1.5 million
operations per second (CIFS, NFS, and iSCSI) for almost 10PB in an area available
for a diverse range of products. In 2010, he wrote ZFS -Para usuários OpenSolaris,
Windows, Mac e Linux, Brasport, the first book about ZFS in Brazilian Portuguese and
actually one of the few books about ZFS available in a language other than English.
He tries to write regularly on his blog at http://www.eall.com.br/blog.

Acknowledgments
First, I would like to thank the open source community for all the hackers involved
in bringing lines and lines of code, documentation, and knowledge into the world.
I would like to specifically thank the Samba project team and community! The Samba
4 software is a huge accomplishment and deserves all our appreciation for the effort
taken in delivering such a great product. I would like to thank all the editors and
reviewers who worked with me during the journey of this book; I would not have
been able to do it without your help and invaluable inputs. I would like to thank my
family: Ana, Júnior, Pedro, and Leonardo. It's all for you! Last but not least, a big
thank you to my grandmother and my mother, Maria Leal. She is the reason I stand
here today.

About the Reviewers
Kai Blin is a computational biologist by trade and an open source developer by
passion. As he is more of a network and systems programmer in his spare time, the
Samba Team member feels lucky to also be able to work on open source software
in his day job. He holds a PhD in Microbiology from the University of Tübingen in
Germany and is currently working on his post-doc in Cologne.
Henry Gultom is a Linux consultant for an IT company that operates out
of Indonesia, Nigeria, and the Kingdom of Tonga. With more than 10 years'
experience in Linux administration, he has acquired a deep technical background
in the management, design, assessment, and systems integration of information
technologies. Since 2010, he has been helping many IT companies in Indonesia to
use Samba 4 and has been successful until now.
Iulian-Nicu Șerbănoiu is a graduate of Politehnica University of Bucharest.
He also holds a master's degree in Advanced Computer Architectures from the
same institution. He is a senior software engineer, with a specialization in imperative
programming languages, such as Java, C++, and Python. He has a passion for free/
libre software and always tries to be up to date with the latest technologies. He loves
scripting languages and uses them to automate tasks as much as possible.
I would like to thank my family for giving me the opportunity to
grow and become what I am today. Thank you very much for your
support; without you, I'm nothing.
