when people login concurrently from more than one Windows 2000 SP3 workstation to my Debian Samba 2.2.3a-12.4 domain, they can't then logout on either workstation, choosing 'log out', 'restart' or 'shut down' produces absolutely nothing. so I'm looking for a means to automatically logout / disconnect people when they login from another workstation and are already logged in elsewhere; anyone know of one? (tho it may not be advisable practice, Windows NT4 Server is happy for people to login concurrently from Windows NT4 Workstation) pete
