[Grok-dev] PluggableAuth / grok-1.7

[Andreas Knote]

Hello,

I'm trying to set up PAU using grok-1.7 and the corresponding ZTK libraries (zope.pluggableauth, zope.authentication, zope.security ..).

I used merlot's auth.py (https://code.google.com/p/merlot/source/browse/merlot/auth.py) as a starting point / guide and tried to port it to the new libraries.

I've managed to get it to compile & run, but I still can't log in. I found out that my UserAuthenticationPlugin is called at least two times on each request to a restricted page and the right Principal is returned on the first but not on the subsequent calls (seems like it loses the credentials in between).

Result: No Login possible.

I attached pdb output below (Excerpts from Login-Form request trying to login as 'joe' / 'joe' ) 

My auth.py:

and app.py:

http://pastebin.com/3w9n12Ld

I would be happy if you could help me.

Andreas
