[Zope3-Users] PAU and Session Credentials

I've created and registered a PluggableAuthentication in my site. I've added 
two plugins: PrincipalFolder and SessionCredentialsPlugin and registered 
both. I've configured the PAU to use these plugins. In the principal folder 
I've created a Principal. I've also created a loginForm.html that looks like 

<form method="post" enctype="multipart/form-data" tal:attributes="action 

  <input class="textType" id="login" name="login" size="20" type="text" />
  <input class="textType" id="password" name="password" size="20" 
type="password" />

  <input type="submit" name="SUBMIT" />


If I try to call a page which reguired a specific permission the loginForm 
comes up. But when I enter the login and password of the Principal in the 
Principal Folder or a the manager principal defined on creation of the 
instance I just get redirected to the login page again. This now was the 
behavior before a played around with the PAU a bit now it has changed to a 
system error:

TraversalError: (Principal(u'pre1'), 'getLogin')

The error log information of the user:

User:  unauthenticated, pre1, CS.User,

pre is the prefix of my principal folder (BTW: what is the sense of this 
prefix), 1 is the object id of my test principal, CS.User the role of the 

I've been stepping in the session credentials plugin code and I see that the 
login and password date is extracted correctly.

Somehow I'm still confused how everything is supposed to work...
