[Zope] Permissions Problem When Adding ZObject

30 Jan 2003

      I'm trying to figure out a permissions problem.  This post from 23 
December describes almost exactly my problem.  Since I didn't see a 
solution on the list, here it is:

I'm getting the same basic error.  With VerboseSecurity installed, I get the error:

    *Error Type: Unauthorized*
    *Error Value: Your user account, Anonymous User, does not have the
    required permission. Access to 'FarmUserClass' of (FactoryDispatcher
    instance at 8adcc80) denied. Access requires one of the following
    roles: ['Manager']. Your roles in this context are ['Anonymous'].

    or

    **Error Type: Unauthorized*
    *Error Value: The object is marked as private. Access to
    'propertysheets' of (ZClass instance at 89d2628) denied.*

When I execute the script, I'm logged in as a manager user as defined in the top level acl_users folder.

The app is a modification of the JobBoard tutorial posted on the Zope.org site (http://www.zope.org/Members/mukhsein/job_board_howto/index_html?pp=1).  The tutorial works in my Zope instance, but the adapted version fails as above. I've done the v. 2.2+ suggestion in the tutorial; it doesn't help either.

I'll add more detail if someone can suggest what kind of information is relevant.  But for now, just finding better information about how permissions work would probably help.

Thanks,
Rob
