[Zope-CMF] portal_catalog items not being returned in query

[Kevin Carlson]

In a CMF instance I am querying the portal_catalog for a specific type like
this:

<dtml-in "portal_catalog({'Type': 'Press Release'})">
 ...other stuff...
</dtml-in>

When I am accessing the site as a manager everything shows up as it should.
However, when I access the site anonymously, I get nothing from the catalog.
I have tried adding various proxy roles to the dtml method to no avail.  Any
idea what could be causing this?

Thanks,

Kevin
