[Zope] Local Roles, User-Defined Roles

[Ben Ocean]

Hi,
For some reason I don't appear able to create user-defined roles at all! 
With regard to local roles, I'm able to create them, but they don't appear 
to have any effect. For example, if I create a local role for pnl as 
manager then change the *access content information* from the acquired 
setting to just manager and owner (as opposed to anonymous), then try to 
access the page, I discover that only user webmaster, the owner, is able to 
access the page. Nor can I change ownership! How should I begin 
trouble-shooting this?
TIA,
BenO
