Thanks for your answer Brad!
I thought of this but what would happen if the browser crashed or was
closed?
The Boolean field would need to reset to zero to allow the user log back in
again but I can't trigger that kind of query without a client request or by
scheduled process right?

Kevin,
add a boolean field to your user table called "loggedin" ...when you query
the table to authenticate check the value of this field...if 0...user can
log in...otherwise "sorry you are already logged in"...be sure to trip this
field to 1...whenever the user logs in.

Subject: Concurrent users and client certificates
Hi all,
I need to meet a business requirement where the same user cannot be logged
in concurrently, i.e. if I log in a kgilchrist from one machine, I can't log
in again from another machine until at least the first session ends.
At the moment users are given a client certificate which I authenticate
against a database and I then set a few session variables to mark them as
authenticated etc. The session vars are disassociated when the browser
closes loses the temp cookie.
As part of the authentication process, do I need to somehow search through
all the other sets of session variables? How would I do that?
>From reading some of the threads on the list it seems that using session
variables isn't necessarily a good thing either. Need to do some
reading....
Thanks,
Kevin
