This is maybe a naive suggestion but if Zope's TTW execution (e.g. Python Scripts) can't find a __roles__ on the object at hand doesn't that just mean that the class wasn't initialized with any security.


class LDAPProxy(Folder):
    ...

from Globals import InitializeClass
InitializeClass(LDAPProxy)

That should set the *__roles__ on all it's methods.

Hi *,

I am trying to have a folderish object that acquires from a user object
(ldapuserfolder). It should have its own properties and contents, but
fall back to the ones of the ldap user.

I have created an object, extending Folder, and it behaves nicely in
zopectl debug. When I try to access it through e.g. a python script  I
get an:

Error Type: Unauthorized
Error Value: Unable to find __roles__ in the container and the container
is not wrapped. Access to 'dn' of test, acquired through (LDAPProxy at
/testfolder/ldapproxy), denied.

I am sure its my lack of understanding of acquisition. I am trying to
bascially put ldap user object 'on top' of the aquisition line (with the
ldapproxy at the bottom), but obviously failing in doing so. Any ideas?

Cheers,

  Joerg
