As far as I know, JMeter does not really simulate
multiple users.  Instead, it simulates multiple
instances (threads) of a single "user".  I know it
sounds a little confusing, but let me describe it
better with a concrete example.  [If any of this is
incorrect, please correct me.  We really need to
clearly describe this in the user's guide.]

The HTTP Authorization table can contain many entries.
However, JMeter does not randomly select a particular
user to login as.  Instead, JMeter looks at the Base
URL you provide and the URL that you are requesting
and.  If there is a match, it will send a single (the
first?) match that it finds. So, you could have five
users with the same Base URL (for example, "/login"),
but only one of these users will be chosen and it will
be the same user every time.

I can investigate it further.  Henrik, if you could
provide us with an example of why you would like
multiple users, then that would help us.

I can think of an example of where this could be a
problem.  Let's say that you have a system and you
want to simulate 100 users.  When you run JMeter, you
will get 100 logins for the same user ID (defined in
the Authorization table).  The application may not
allow a user to be logged in multiple times.

I think we have a similar issue with cookies.

Comments, questions?  

Thanks,
Kevin Hammond
