Sorry for not understanding and thank you for all the help...
How do you create another user folder?
What do you mean by "keep users like this
around in a different data structure"?
I currently am only using one user that is called "Intranet User", is
there an easy way to setup so that it just looks at that Users domain
and not any other. I am not good enough with Zope to understand a lot
of these concepts.

The only real solution is to create a different user folder
implementation that doesn't handle domain auth so stupidly. For
instance, designate a user as a "domain user" and keep users like this
around in a different data structure so you don't need to iterate over
all users to find one that matches the domain spec.
