During a recent conversation with a field engineer about a client who needed to replace their server, we discussed how the client was going to have a heart attack when he discovered how much the replacement was going to cost. The hardware cost was doable; the cost of the Client Access Licenses (CALs) is what would send the client into fibrillation. It didn't seem to matter which way the client went with the CALs, the cost was going to be astronomical ($30,000+). Fortunately for the client, he had the budget for the server and the CALs, so he went with that particular setup. This particular client was not interested in an alternative solution, but the discussion lead to me talking about how clients could replace a Microsoft Windows Server environment with open source software. I know it is also possible to replace the Windows Server platform with a Linux platform like, but the goal in DIY projects is to save serious cash, and with Red Hat Enterprise Linux, there will be a bigger cost than just the hardware.

CentOS is based on the code from Red Hat Enterprise Linux and is 100% binary compatible with the Red Hat release. Authentication The Linux platform does not have an Active Directory; it does, however, have the system Active Directory was based on — Lightweight Directory Access Protocol (). LDAP is a protocol for reading/editing directories over a network. This allows for such things as user authentication and records storage.
When LDAP is set up properly, it can serve a business in a similar way that Active Directory does. Although LDAP is not the easiest system to get up and running, once you get it up and running, the service is solid and reliable. Related resource:. DNS The name system is the most commonly used DNS system. Unlike LDAP, BIND is fairly straightforward to install and configure.
It can be installed and configured in about six easy steps, so this portion of getting the Windows Server replacement shouldn't be much trouble. If you are sticking with CentOS as the platform, the installation and configuration of BIND will be even easier. When using the Linux OS as a server platform, is the web server of choice. Apache is incredibly reliable and scalable, and it's also amazingly simple to install on any platform. In fact, the installation of a full-blown Linux, Apache, MySQL, PHP (LAMP) server can be completed (once the Linux part is done) with the command tasksel. (The tasksel command only applies to Ubuntu and Ubuntu-derivative distributions. For the installation of Apache on CentOS, more than one command is necessary to install constituent pieces.)
