[Zope] ZODBCDA fails under 2.2

I'm trying to access data via the ZODBCDA latest build and Zope 2.2 Whenever the ODBC query returns data, the user is challenged for authentication. Pages that do not use ODBC and database methods that return empty sets are not challenged. Has anyone else encountered this? In my configuration, anonymous has acquired "Access", "View" and "use db methods" rights. I've also tried with explicit rights.
