Hi, I'm writing my first PAS plugin for Plone. I'm a little bit in
trouble because I don't find a very simple tutorial from A to Z which
explains me how to create it.
I understood only that I've to create 2 py files: one ontaining
initialize informations and another one with py class which contains
the implementations of interfaces.
Can somebody explain me better what PAS needs to run my
implementation? I would like that it would be displayed on /acl_users/
plugins on the section Authentication Plugins.
Next I'll attach my sources which are my "bad" iplementation of PAS
plugin. Is it some near my implementation or have I missed all?
