Thats very interesting.  We are utilizing Samba 4 for our Active Directory
implementation, and for the most part we leave it alone from a development
stand point, at least now anyway.  Samba is a very thorough and stable
solution, so I'm not sure there would be much advantage to us, at this point
anyway, to try to assemble a different technology.

In a nutshell, Resara Server is taking existing technology and making it
accessible and easy to use by anyone, regardless of Linux expertise.  The
management tools, packaging, and support are our development priorities.
