An Introduction to PostgreSQL - Part 4

The Release of Samba 4.0 - First Free Software Active Directory Compatible
On Tuesday 11th December 2012 the Samba team announced the release of Samba 4.0 containing the first compatible Free Software implementation of Microsoft’s Active Directory protocols. This is great news as it is sure to be the beginnings of bridging the gap between the Open Source world and the Microsoft World. Containing an admirable quote from Director of Development at Microsoft; Thomas Pfenning this could be a remarkable start to further development in other areas. Sirius has implemented Samba for many of their projects and long term clients, including Specsavers.
