[Zope] Insecure Debugging

Greetings, I'm getting 401's when I try to debug my Zope site using pdb. This is my start-up script: *********************** import sys sys.path.append('Path to Plone') import Zope, ZPublisher from AccessControl.SecurityManagement import newSecurityManager def zope (url): app = Zope.app() bsimon = app.acl_users.getUser('admin') newSecurityManager(None, bsimon) ZPublisher.Zope(url,d=1) ************************ Any ideas? Thanks Joseph
