I dint want to built customized login page in 1st place. Actually this
is a Govt. stores management site used in my state only bulit all in
ASP. I 've to convert this into a Zope and Plone version.
So i wanted to get it converted with minimun changes.
But now as you say i think I should go the way Zope does it . only
that i'm finding it hard to customize it in Zope.

So i think 2nd structure is abetter fit.
Now the qusetion is how do build this district user folder structure
using the database?
Hope not manually, because there are 22 districts and about 15 users
in each of them pluys head quarters.

simpleuserfolder components ?

I dont need the password but do need the username and district for
following pages to decide the access rights and the stores available
inthe districts , also for some report labels.

i dint get to know much about coding ZPT's and Script(Python) for them,
from the ZPT refs and Zopebook. So wanted some simple working examples.

Are these above said things not possible in exUserFolder. how do i
customize it for my problem?

So this is what can be done if I use exUserFolder ?
