[CentOS] Login Feature

I asked one of my team mates to evaluate centos 5.2 as a more stable
distro for our business use than Fedora which we have used for years.

His main objection so far has been the lack of a neat feature of
recent Fedoras (at least since 7) that allows a user to login as
himself if the screen is locked by another user (a switch user
feature).

Is that feature available or is it planned?

Thanks.
