[Zope-PAS] Problems Upgrading PluggableAuthService

[Mark Phillips]

I have a plone site running:

Plone 2.5.5, 
CMF-1.6.4, 
Zope (Zope 2.9.8-final, python 2.4.4, freebsd6), 
Five 1.4.2, 
Python 2.4.4 (#2, Sep 26 2007, 13:07:27) [GCC 3.4.6 [FreeBSD]
20060305], 
PIL 1.1.6
membrane 1.0
remember 1.0
PluggableAuthService-1.4.2

The members cannot add portraits to the site, and I get the error
"ValueError: Property portrait: unknown type"
when I do a search for all users in site setup.

I looked at the bug reports and found 2 that relate to this error: 
http://plone.org/products/remember/issues/44
http://plone.org/products/remember/issues/32

The suggested solution is to upgrade
PluggableAuthService to version 1.5.2, which I did. I stopped zope, 
removed PluggableAuthService v 1.4.2 from the Products directory, 
installed the new PluggableAuthService v 1.5.2, and restarted zope. 

However, no one can log in now. The remember members are still alive 
and well, but entering the use name and password does nothing - 
no error, no logged event, just return to the login page.

What else do I have to do to upgrade PluggableAuthService?

Thanks!

Mark
