Creating Trusts between UCS Samba/AD and Native Microsoft Active Directory Domains

Logo Samba, Sprechblase "what do you think"

In this article we would like to inform all IT administrators and IT-interested people about the possibilities of a trust between two domains (UCS Samba/AD and Microsoft AD). To set up a trust is to give users of one domain access to the resources of another. This can increase the scope for actions in some situations!

In our example, we will specifically refer to the interaction between Samba in UCS and Microsoft Windows, explaining in detail how a so-called trust relationship can be configured and informing about the current state of implementation.

Summer time is conference time in the IT world and anyone going to one or more of these events hears about the latest developments in cloud computing, wondering sometimes how to keep up with the sheer number of cloud services acronyms used in this industry.

How to Install Open Source SuiteCRM and Empower Sales

The core sales tool for every business in our increasingly data-centric world is customer relationship management (CRM). Your sales benefits greatly from CRM by collecting the best data of your leads.

There are numerous CRM solutions on the market, each with their unique advantages. In my opinion and personal experience the Linux-based software SuiteCRM stands out as it offers a comprehensive and easy to use user interface that is ready to use out of the box, but can also be easily adapted to your unique situation if needed. SuiteCRM provides easily understandable overviews of your customer engagement process. Apart from lead and contract management it also includes project management, invoicing modules, further extensions, and it is open source.

With the following installation and operation guide I like to help you get SuiteCRM set up and running. Look how you can manage it with ease via UCS!

Brief Introduction: SAML

Schaubild Übersicht SAML

Web-based work has been a widespread phenomenon in many industries for a long time already and is increasingly become standard practice thanks to the recent trend of cloud computing. This all sounds great to begin with, as you also have access to web-based programs from outside of the company and are thus able to work from practically wherever you want, whenever you want. However, the direct consequence of this flexibility is that each user has to remember more and more login data for the individual programs for security reasons. Added to this is also the time and effort required every day for logging in and out of each program, depending on how many programs you work with in parallel.

Luckily, this is where SAML – security assertion markup language – comes into its own. SAML is a secure, XML-based data format for the exchange of authentication and authorization information so as not to put a company’s data security at risk despite web-based working. At the same time, it also offers each and every user an optimal level of comfort.

OX in a Box: A Self-Contained Open-Xchange Environment for Containers and Virtual Machines

Schaubild OX in a box

Container technologies like Docker make it possible for service providers to easily offer separated, private environments containing Open-Xchange and other services at a low footprint. But usually management of these services is a challenge.

Univention provides a complete open environment to run and manage Open-Xchange inside Docker and popular hypervisors. This includes life-cycle, patch and identity management (IdM), a management GUI for customers, connectors to Microsoft Active Directory, and the possibility to integrate a dozens of other applications.

Brief Introduction: Single Sign-On

Single Sign-On Schaubild

The increasing number of programs that employees in companies have to deal with day in, day out makes their work not only easier but also increasingly more complex. In addition, a higher number of applications also translates to an increasing security risk for the data in the corporate network.

We would now like to take this opportunity to explain how you can make work easier for your employees with single sign-on technology and keep your data safer from external attacks at the same time.

Secure Operation of Existing Applications in the Corporate Environment with Open Source Tools

Last year I submitted my Master’s thesis titled “Secure Operation of Existing Applications in the Corporate Environment with Open Source Tools”, and successfully earned my degree in IT from Bremen University of Applied Sciences. My research focused in particular on the differences and the security-related advantages/disadvantages of server virtualization compared with operating system virtualization, which had undergone much less intense testing at the time.

As I can imagine that this is a topic which will also be of interest to some of you too, I decided to summarize the most important findings of my work here:
