How to install Univention Corporate Server



Most of the IT or non-IT organization/companies generally possess hybrid environment .i.e. they have Linux based as well as Microsoft based desktops or servers.It becomes a challenge of IT/System administrators to ensure availability of all of the resources such as printer sharing, directory sharing, Internet sharing etc, especially when some organization is looking for some low cost solutions for such resource management. Although a lots of firewalls are available in open source but very rare dedicated OS are available which can act as complete All-in-One IT infrastructure management solution provider. Zentyal is one of such available application server, a article based on zentyal was published few months before refer following link to know more about zentyal

We were searching for some other alternative and we found uninvention corporate server as alternative open source which can be used in the form of complete IT infrastructure management Application.
