Unfortunately, this is correct. The PAS is gone. It was one of those bits in 
the book that I knew would be a problem with Zope 3.1, but could do nothing 
about. :-(

Okay. IPrincipal is used though. The strategy changed from PAS to PAU. In PAS 
a principal always existed, once you created it. In PAU, only information 
about the principal is stored and the principal (providing IPrincipal) is 
created once the authentication was successful.

The principal annotation views (can you actually give me some names?) could be 
easily fixed by working with IPrincipalInfo objects instead IPrincipal 
objects. This step should not be too hard.
