[Zope] LoginManager disrupts access to protected object above it

[Itai Tavor]

Hi,

This problem started with failure to access Control_Panel, which I 
thought was due to a SiteAccess problem... but I now tracked it to a 
problem with an instance of LoginManager.

I have the following setup:

Zope 2.3.0b2
ZPatterns 0.4.3b2
LoginManager 0.8.8b1

Zope/
     test1 (PythonScript) requires Manager to view
     folder/
         test2 (PythonScript) Manager proxy role
         acl_users (LoginManager)

test1:
     return 'spam'

test2:
     return container.test1

Calling test2 results in the traceback attached below. If I remove 
acl_users, test2 works. The LoginManager is a bit tricky, as it uses 
a virtual UserSource loading user objects from an external 
Specialist, but it seems to work in every other way. I have no idea 
if this problem is due to a bug in my LoginManager implementation or 
a general LoginManager bug.

Can anyone explain this or suggest a way to find out what is going wrong?

TIA
