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?
