Let me show you here not only how to do this but also explain the various options for receiving and sending mails. In addition, I will describe how to configure the users.
Our work environment is becoming more ‘colorful’, but also more difficult to handle and control. Employees increasingly determine for themselves which tools they use and where they work. As an admin, you easily lose track and become afraid of losing control over the security of your corporate IT.
Fortunately, UCS provides an identity and access management (IAM) that centrally manages and supervises all tools, devices, data, and accesses. By setting up a centralized IAM, you not only avoid shadow IT, but most of all, you regain control over your network and your precious data.
For those of you who have little technical knowledge in UCS, I like to explain today the terms LDAP / OpenLDAP, as they are the cornerstones of our central IAM system.
Would you like some valuable tips on how to increase network performance and user data availability when using Windows clients together with UCS?
Thinking about user data, many of us admins immediately understand that questions about the issues of backups, privacy, and availability, no matter whether across different machines or outside the office, can create us a considerable headache. But fortunately there are solutions in place and in this article I want to cover two of them.
E-mails have become an integral part in our everyday lives. In business anyway, but they have also found their way into our schools. However, schools face the same problems that have long been known by organizations: School authorities with thousands of students, hundreds of teachers and many administrative employees offer hackers a target at least as worthwhile as other large enterprises.
In this article, I’ll show you some simple yet highly effective measures that you as the administrator of a corporate IT or school IT can take to effectively protect your users and mail servers from hacker attacks. As massive spams are not only annoying or even dangerous to us all, they can also cause other mail servers to mistrust your email servers so that your users will no longer be able to send regular mails.
DHCP and DNS are the two fundamental services in an IT network. Whilst DNS makes sure that servers, clients, and services can be found in the network, DHCP ensures that the clients in the network are also provided with the information they require to participate in the communication.
In this brief introduction we want to give you an idea of some important concepts for identity and access management (IAM), and of the related challenges organizations face. We will also see how IAM is one of UCS strengths and why UCS is being adopted by large companies, and by governmental institutions, to manage tens of million identities.
When recently assisting a customer in choosing a new cloud service provider, the providers of choice offered 95%, 99%, and 99.9% availability labeling their service “High Availability”. For the human brain and considering a scale from 0% to 100% all of these numbers sound rather good, and we would naturally think, that these services almost never fail. However, let us have a closer look at what high availability truly means for IT environments and how it affects UCS and let us think about why you should also consider the time to recovery and planned downtimes.
