Agreed again.  (I think you meant something different from the facility John
Terpestra referred to - on NT/2K you can specify which machines, perhaps
only one, that a user account can use, but you can't specify "Maximum number
of concurrent sessions"; on Netware you can do both.)

Mmm.  I've only *just* managed to demonstrate to the Powers-That-Be around
here the full horror of an unswitched LAN with unencrypted passwords and a
sniffer ... so _now_ changes are underway.   Password encryption *with*
failed login tallying *will* be part of security policy ..

I'd just like to add a vote for another item for this list - something which
can be done on Netware, VMS, and on some Unixen, but not NT/2K (AFAIK) -
allow a password expiry "grace" period to be configured if desired - a
period of time after a password has expired, during which a user account can
still login but is forced straight into a password-change dialog.  This
allows for those occasions when (e.g.) someone is away for a whole month,
during which their password expires.

Likewise, but only for documentation ..
