Hi all, I've just find a solution for athenticate on active directory in shared networking mode. I've to join the domain in bridged mode first (no way in shared and in host with nat things found on the forum). I create a file called sysctl.conf in /etc which contain : net.inet.ip.forwarding=1 net.inet.ip.fastforwarding=1 Restart you mac. It enable ip forwarding on all interface. Now configure your virtal machine in shared network mode. Start it, and active directory authentication work. The only thing I don't have is network browse (in network favourites). But if I type \\servername in address bar in explorer it connect well. Hope this can help some people.
