Done, thanks.

Ok. This is the first Samba DC I'm playing with and I like to check 
everything before putting it into production.

I've replicated sysvol with robocopy (from the Windows) and configured a 
task to keep things in sync till the Windows DC will be demoted.

What about the strange chars in getfacl output? They seem like escape 
"default:group:BUILTIN\134administrators:rwx" should read 
"default:group:BUILTIN\administrators:rwx", right?

Is there something wrong here?
