Re: Blocking Access to Non-domain computers

[Don Voss <voss () albany edu>]

Have you considered using a dhcp authorization method like netreg ?

http://www.netreg.org/

It, netreg, can do much more .. such as check on win patch levels 
before, notify & redirect before allowing a device on the wire .. but at 
its base level it can authenticate against a pop server for a valid 
account [user account list], harvest the mac address, allow static name 
generation, etc. I think it can be linked to ldap instead of pop .. 
check it out.
