Cannot traverse to /manage when running under Zope 2.13 and paster

[nateaune]

I'm running Plone 4.0.1 under Zope 2.13 using paster, and when I go to http://localhost:8080, I can see the welcome text "Plone is up and running", but when I click the button to "Create a new Plone site" (http://localhost:8080/@@plone-addsite?site_id=Plone), I get a blank screen.

The same thing happens if I click on the "Zope Management Interface" link (http://localhost:8080/manage). In Lynx, these links give me a 401 error. Does this mean I need to authenticate using repoze.who?

Here is a traceback of the internal server error if I try to access http://localhost:8080/Plone

$ ./bin/paster serve zope2.ini

Please note that I did not use the "addzope2user" script, because I presume that the Zope admin user has already created for me with the plone.recipe.zope2instance buildout recipe.

You need to have repoze.who as part of the WSGI pipeline to handle Unauthorized exceptions.
