I am trying to learn zope2 for the last couple of months, reading and doing zope2 documentations and sample file based python product developments.

I know Zope s advanced a lot more than a decade(and zope3 / bluebream is the there now) but I just started few months back, sorry for my ignorance and lack of opportunity to start at the early stage.

I have gone through zope2 docs and other tutorials on zope, and tried a couple of file base zope products.

But I am unable to find/ do a complete user registration module for zope sites.   and small session handling applications like a shopping cart which use session management techniques.

1 how zope.org is doing user login/register/password retrieval module, or how people like you add a user registration/login/password retrieval module for your zope sites.

I searched a lot and learned the acl_users folder properites,

and can do manually add users    with these code excerpts.

self.manage_addUserFolder()

    self.acl_users.userFolderAddUser('user1', 'passwd', ['Member','Admin'], [] )

self.acl_users.userFolderAddUser('user2', 'passwd', ['Member', 'Managers'], [] )
self.acl_users.userFolderAddUser('user3', 'passwd', ['Member', 'Manager','Admin'], [])

etc. but unable to do a user registration module using acl_users and its web interface .

By reading BetaBoring and some other tutorials in upfront systems zope course, devshed.com tutorials I think   I am in the right track of zope2 learning.

2. I have done a sample application,   but I dont know how to clear the normal zope user credentials when a sample user clicks   a logout   link

here some sample code :

I added an anchor       <a href ="logout" > Logout </a> tag   for logout in my   pageTemplate name as myPage.zpt

from AccessControl import ClassSecurityInfo
security = ClassSecurityInfo()
security.declareProtected('adminroles', 'myPage')
myPage = PageTemplateFile(
                    os.path.join('views', 'myPage.zpt'), globals())



and I added few sample users   such as user1,   user2, user3 etc to acl_users with sample password 'passwd'

        self.acl_users.userFolderAddUser('user1', 'passwd', ['Member','Admin'], [] )
        self.acl_users.userFolderAddUser('user2', 'passwd', ['Member', 'Managers'], [] )
        self.acl_users.userFolderAddUser('user3', 'passwd', ['Member', 'Manager','Admin'], [])

and when I access the   protected page 'myPage' it asks me for acl_user credentials and I am able to enter   sample users and password and it allows me to view the page 'myPage'

But problem when I click the Logout Link in the myPage( <a href="logout"> Logout</a>)    then it call a logout.zpt
page template there I display a message you logged out , and return the login.zpt    page.

but   in the login.zpt page if you enter anything   I mean garbage for username and password field   it allows to view the myPage.( this happens once you logged in first time with the credentials).

How to clear these zope acl_users credentials once you click the logout link which in turn call a logout.zpt template.

If you have some sample / demo applications to show how to do these issues, can you share me those. I am stuck in this point in zope.

if any such application code/related works to follow it will help me a lot.

Thank You
