Bear in mind that YP really only passes information from the YP master
to the slaves, not vice versa or between the slaves - hence, one slave
has no way of knowing what's happened on another.

If you mount home directories via NFS you could do something evil with
user's login scripts and a lockfile in their home directory, but I
would not advise that.
