Hey guys,
I am currently plaing with the 2.8.1 code and openid4java.
But I am having a hard time trying to fiugre out where exactly to hook
in the OpenID stuff.
The problem is (as also described in #JSPWIKI-94), that:
1. To me it seems you cannot do the whole thing in JAAS:
OpenID as I understand it has two phases :
Phase I:
- The user just submitted his openid identifier to our login/
registration from.
- We do discovery on the identifier to find the Endpoint of his OpenID
Provider (and check if the provider is in our whitelist)
- We redirect the user to his OpenID provider
So in this phase it makes no sense to me to use a JAAS-Module since we
wouldn't be able to complete the login mehtod
as we do not know enough about the user yet (we do not know if his
identity is asserted by the OpenID Provider).
So I currently do this via JSP and Scriptlets (no custom tag yet).
Phase II:
- The user is redirected back to us by his OpenID Provider
- We connect to the OpenID Provider to verify the assertion that was
passed along the request (be it a positive or negative assertion)
- Now we know enough about the user to log them in.
I currently try to use UserManager.setUserProfile in this situation.
Now here comes my Problem:
I would like to do all the assertion verifiaction in a JAAS-Module,
but for that I need all the request
data, which I do not have in the setUserProfile-Method.
So currently I am stuck. Before I start to wildly mess the API: Am I
taking the right direction?

Hi!
Thanks for the effort - sounds like a worthy project!
I think you will save yourself a lot of grief if you work on the
2.8.1 branch, since the trunk is now the subject of a lot of changes
- but note that we *will* be making some rather major changes for
3.0, so you may face a small porting effort towards the end. We
certainly wouldn't like to land a major feature in 2.8 branch
anymore, since it's rather stable.
I think the first thing you could do is to outline your plan as to
how exactly are you planning to hook into our structures - a good
place to start is probably the Security documentation at http://doc.jspwiki.org/2.8/wiki/Security
, and then asking a lot of questions on this mailing list.
Also, since we are talking about a fairly large project here, you
might want to sign a contributor license agreement (CLA), and
depending on the German copyright legislation, get also Heilbronn to
sign a corporate CLA. That, or Heilbronn (or you) need to, at the
end of the project, give a software grant (SGA) to Apache Software
Foundation. But these are not biggies and can be tackled if/when we
start merging ;-)

Hi JSPWiki Devs,
I am a student at Heilbronn University in Germany (Some of you
might know Christoph Sauer, who worked there.)
As pre-thesis for my diploma I want to enhance JSPWiki with OpenID.
I am still pretty new to JSPWIki, OpenID and JAAS.
I have worked my way through the official OpenID 2.0 Authentication
standard
and will do as well for Attributes Exchange.
I would like to base my work on the 2.8.1 tag and
see to get it integrate into the trunk later. Is that the correct
way to do it?
As I see Andrew already spent quite some time on OpenID and did
some preparations.
Since I plan to get my diploma somday soon (say in 2009 ;-)), I
have a high personal interest
in getting OpenID into JSPWiki.
Summary:
* I have time
* I have motivation
* I need some help to get started ;-)
Any suggestions where to begin? I guess registration/profile
creation would be first.
kind regards
