[Zope] How can I limit one user id to be able to log on at one location at one time?

[Lily Li]

Hi,
Our site is using zope v2.3.3 and CMF v1.1. I've got a requirement to forbid
simultaneous log on with one user id at different locations. Does CMF
provide this feature? Or is there any way I can do it?
Thank a lot in advance.
