I also had similar problems and added a question to the faq:
http://wiki.zope.org/zope3/FAQ#having-defined-and-registered-a-pau-in-the-root-of-the-site-i-cannot-log-in-as-a-user-with-zope-manager-permission-anymore-help
Having read FB's description, I now understand that the text is wrong,
but the method is ok to remove the IAuthentication utility.
I will correct the text description tomorrow.

Hi,
I'm trying to set up a user folder for my site, but i cant get the PAU to work.
I add the Pluggable Authentication Utility object, register it, add
PrincipalFolder and SessionCredentials plugins and register them. Add
a user in the Principal folder. But then i try to login, i just get
redirected to the same login form and nothing happens.
What else do i need to do?
This is what has to be done (in the right order!):
1. Add a PAU
2. Make sure, the PAU knows some users - e.g. this way:
1.Add a principalfolder
2.Add a principal into the folder
3.Configure the PAU to use the principalfolder
3. Make sure, the PAU is able to extract the credentials correctly
(Session-Credentials are usefull for that)
4. Register the PAU
Once the PAU is registered, the default IAuthentication utility which provides all the
zcml-predefined principals becomes invisible (speak: "useless"). This means, you don't
have a manager any more and you're unable to unregister the PAU again.
For that reason, I wrote a Auth-Plugin which is like a principalfolder but all
principals
defined there are managers.
However: I wrote a Mini-Howto on how to remove the registration of a PAU
manually.
Unfortunately it's in german:

-> Please correct me if I'm wrong.
