Hello grokkers,
I use the chapter 7 on the security of the "grok 1.0" great book from
"De la Guardia".
where there is an auth.py module beginning by the following import
lines.
import grok
from zope.app.authentication.session import SessionCredentialsPlugin
from zope.app.authentication.interfaces import ICredentialsPlugin
from zope.app.authentication.interfaces import IAuthenticatorPlugin
from zope.app.authentication.interfaces import IPrincipalInfo
from zope.app.authentication.interfaces import IPasswordManager
from zope.app.security.interfaces import IAuthentication,
IUnauthenticatedPrincipal, ILogout
from zope.securitypolicy.interfaces import IPrincipalPermissionManager
from zope.securitypolicy.interfaces import IPrincipalRoleManager
from zope.app.authentication.principalfolder import InternalPrincipal
from zope import component
from zope.interface import Interface
from zope import schema
As admin I create one project, which can be accessed by
http://xxx.xxx.xxx.xxx:xxxx/todo/0
As admin I create a user ("user1").
Then from one other browser I address the project with the address.
http://xxx.xxx.xxx.xxx:xxxx/todo/0
As expected the login page is displayed.
I enter the user "user1" with the password.
After the click on the button, the following lines are displayed.
URL: http://xxx.xxx.xxx.xxx:xxxx/todo/%40%40login

Did I miss something or the code should be updated for the version 1.1
of grok?
Thanks in advance for your help.
