[ -*- Sorry for the long mail -*- ]
I need some advices to use Principal / PrincipalSource. I'll try to describe
briefly the context :
I've got a completly separate "server application" on which a user can
connect using host/login/password. Once the user is connected, he can
make several queries and the server-side API is quite similar to the
DB-API. As you can see, it's juste a quite common use case.
OK, so I've got this app, and I've also got a Zope3 instance on which I would
like to have pages that go and query this remote app and finally display
the received results.
I'm new to Zope3 (and don't know Zope2), so I've followed step by step the
Zope3Book (The "New principal source plugin" chapter), but I still can't get
First of all, the configure.zcml's browser directives listed in the chapter
did not work for me. I had the following error :
exceptions.KeyError: u'add_principal_source' in:
File "/home/adim/[...]/erudi/repoauth/configure.zcml", line 32.2-41.5
label="Add Erudi Principal Source"
menu="add_principal_source" title="Erudi Authentication Source"
So I changed "add_principal_source" into "zmi_actions", but I then had
to add a "browser:addMenuItem" directive to make the new link appear.
I've then created a simple page ("homepage.pt"), and I've restricted
its access to Site Members, but what I want is to authorize every
authenticated users (including users authenticated against my
new principal source).
How can I do that ??
I think the solution is to map the "SiteMember" role on each principal
but when I try to do this, the following exception occurs :
2005-01-06T17:28:29 ERROR SiteError http://libra:8080/Intranet%20homepage/@@PrincipalRoles.html

I'm a bit lost here ... Do I need to register myself my principals into the registry ?
Any help would be welcome.
P.S. : can anyone tell me what are all the "metaconfigure.py" files ?
