[Zope-CMF] User folder in subfolder

[Jens Wolk]

Hi everybody,

(Zope 2.5 / CMF 1.2)

I try to set up a "demo" area in a CMF site, in which visitors can log in as 
user "demo" and act as a "Manager". This looks like this:

CMF_root
|- demoFolder
|- secureFolder

I created a User Folder "acl_users" in the folder "demoFolder" and created 
the user "demo" with the role "Manager". 

But how can I provide a mechanism so that a visitor can login as user "demo"? 
When he clicks on "log in" (from within demoFolder) in the actions_box the 
login doesn't work (probably because the user user/password is checked 
against the users in CMF_root; the variable "came_from" isn't defined in 
login_form).

For testing purposes I took away the "View" and "Access content information" 
permissions from the Anonymous role. Then I went directly and anonymously to 
http://www.mysite.com/CMF_root/demoFolder. Just as expected Zope asked me for 
user/password. But still the login failed (although the variable "came_from" 
now is defined in login_form).

Again, for testing purposes I created a user "demo" in CMF_root, too (giving 
him the role "Member") and now it worked. But this isn't what I am expected 
to do, is it?

Any hints are very welcome.

Jens
