If you are going to use Plone I can't offer advice - I have looked at Plone on three separate occasions, and recently read The Definitive Guide to Plone, and have stil decided not to use it. I only say this to make it clear that many applications are built without CMS and Plone.

Two separate tables with User information is awkward! The user folders I know of expect user information to come from one source. So you either have to create two folders, each with its own acl_users (provided by one of the User Folder Products), or you have to hack the User Folder product to put in a Union select statement in place of a simple Select.

You have not said whether the people in the different districts do completely different things with different forms, or identical things but specifying the district. If the former then it is no big deal to create the folders manually, although it can be done programmtically. You could set a Local Role equal to the district name and get that role for users from the database. That way, users can only enter their own district folder. If the latter, then you could retrieve the Username and District from the User object for use in the forms (include the District as a role).

Try working on the rest of your application to build up ZPT and Python experience. As I said, managing users is tricky. Also, be aware that Zope experts advise developers to produce file system based Products. There are lots of simple Products that you can use and browse the code to see how they work.

Customisation of the login sequence is quite difficult for Newbies because there are lots of different ways to approach the problem - you have already tried some. I suspect that trying to match what was done in PHP may be part of your problem. It would be helpful to know if your lists of users are coming from one source, like a database table, or multiple sources, like multiple tables or different databases, and whether users are unique in each district
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.
1> the district name and their users come from 2 seperate Mysql tables. the users are unique in each district.
From there you decide your zope folder structure. It could be like this:
site_home |__acl_users |__district1 |__district2
or like this:
site_home |__district1 | |__acl_users |__district2 | |__acl_users
In the second case you would not have to worry about asking the user for the district name. In the first case you would get a district name or a user defined role for that district from a supplementary data source, like a database.
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.
A combination of exUserFolder and MySQL would do.
i don know about them, something like mysqluserfolder or simpleuserfolder components ?
You can get information on the logged in user (Username and Roles) from
the User object, so you don't need to expicitly use sessions at this
stage. You should certainly not store passwords - that would be a serious breach of confidentiality.
Maybe you should say what you do with the District parameter after the
user has logged in.
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.
Giving advice or examples on ZPT and Python for an approach that is probably wrong is just too time-consuming.
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.

I have been trying to think of ways of providing specific pointers, So, assuming you have a custom login page and a custom python script that processes that page:
In the Python script you could set a cookie for the District:
where district is the name of the District field in the form. The District parameter is then always available to your page templates and scripts in the REQUEST object.
At the end of your login script you would typically redirect to some specific page like this:
in exUserFolder you don't have to do anything else - the login works by magic, which is very confusing.
Are these above said things not possible in exUserFolder. how do i customize it for my problem?
Now for the problems:
If the login is wrong the system will call /standard_error_message, so you have to customise that to send the user back to the login form with a Login failed message.
If the user bookmarks a protected page and tries to jump to it without being logged in, the system will call the login sequence starting in acl_users, so you have to customise that to call your own login page.
After the user has logged in, whenever you need to get the Username you would typically use a python script like this:
from AccessControl import getSecurityManager return getSecurityManager().getUser().getUserName()
So this is what can be done if I use exUserFolder ? Hope a reply soon.
