[Zope-dev] Problem writing user folder

[Alexander Staubo]

In writing my NT domain authentication folder, I'm having some problems
deriving a new user folder product. Everything works, _except_ Zope
refuses to authorize the user, even though the authentication
technically succeeds; I see that object traversal accepts the user, but
it's Zope's document rendering thing that denied the authorization.

The problem seems to boil down to a problem with BasicUser and its
allowed() method.

If I override BasicUser's allowed() method (which is aliased as
"hasRole") and explicitly return 1, no problem.

What's weird is that Zope's implementation of BasicUser.allowed()
actually raises an exception, and this is the reason that it does not
validate the role:

Traceback (innermost last):
  File "\tools\zope\lib\python\AccessControl\User.py", line 204, in
allowed
    if not parent.aq_inContextOf(self.aq_parent.aq_parent,1):
AttributeError: aq_inContextOf

It's the damndest thing. I'm thinking perhaps my user instance is
acquisition-crippled, but my folder's validate() method _is_ doing this:

    User = User.__of__(self)
    ...
    return User

If it's of any relevance, I've used the etcFolderUser product as a
template.

I'm sure it's pretty simple. If need be I can send the actual code.
