Instead of removing the lock on your workstations (big security risk
as others have mentioned), why not rather activate the 'user switch'

If you really need to access a workstation, you can then log in as
another user (e.g. admin user) and then do what you want (which may
involve killing the guilty session).

In gconf-editor, you find this option under:

You can then probably apply it system-wide using recommendations of
this thread (I haven't tested it).

I quickly scanned through the thread, so maybe somebody suggested that
already, sorry for the repeat in that case.

A bit OT, but something related that I discovered recently: you can
explicitly start the screensaver (and thus the lock) with Ctrl+Alt+L
(instead of looking for the button in the GNOME menu).
