ADWS / AD Powershell compatibility

Samba does not support many of the AD PowerShell commands that manipulate AD objects, as these are backed by Active Directory Web Services on a Windows DC.

There are quite a few useful things Powershell can do and do simpler than earlier approaches with VBScript.

So it would be useful if Samba provided this interface.

Thankfully a prototype project has been built by Catalyst's Samba Team.

This proof of concept was built to prove the understanding of the protocol, and was tested with

AD-GetComputer 

it is likely that other AD-Get interfaces also work.

It has not been reviewed for security and directly accesses the Samba AD database in sam.ldb
