It's not up to me to decide (and implement) the OS updates :-( and
thus cannot do anything about the status of security of the systems.
Though I completely agree with you :-)
Now to the Samba ADS integraztion problem. I only need to execute the
net ads command, I need the windows domain membership for a service
running on this system not for local logins.
