[Zope] RE: Different Login Screens for Management and User?

[Stefan Langerman]

I was working on the same kind of problem (see my earlier post today),
and I think
I found some solution, thanks to the many hints here and in the zope-ptk
list. It's
actually quite simple.

The trick is to play with exceptions. In your standard_html_header,
include something
like (replace 'Member' with the role you want):
<dtml-unless "AUTHENTICATED_USER.has_role('Member')">
   <dtml-raise type="Please Login!">
                <p>Please login before entering!<p>
   </dtml-raise>
</dtml-unless>

When the error is raised, the standard_error_message is called, so from
there,
you can do some more tests and go to the appropriate login page. I have
not
fully tested this yet, but I think it should work. I think if you put
type=Unauthorized in the dtml-raise tag, you should get the usual HTML
login instead of the error.

Anyone has a better (more elegant/original/creative) solution?
