netbsd as domain controller

[Ezequiel Reyes Aragon]

Can anyone direct me to useful information on configuring NetBSD has a 
domain controller for Windows based networks? I have searched in the net 
and archives for this topics but have found no definite information. Is 
there anyone using samba4 for this with NetBSD. I think it has not been 
ported and compiled for binary packages yet.
