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:
