hey shiva,
i finished exactly the scenario you depicted yesterday:
the many advantages of xwiki (as blog and wiki engine) combined with an
advanced forum, that takes into account the discoursive nature of
knowledge development in enterprises as well as in non profit contexts.
in brief, there are two major issues: authentication and authorisation.
fortunately the xwiki developpers have done a good job in providing a
configurable mechanism to switch the authentication class
(see xwiki.cfg or the respective section in the admin guide)
You implement the XWikiAuthService and probably the XWikiAuthenticator
interfaces and at the next login, credentials are verified you defined
in these classes. i do an (layered) access to an existing application
(the forum part of your scenario; it's not necessarily the better user
management, it simply was there first).
a little trickier is the second issue, authorisation.
i decided to let the quite mature user / group / right management
systems of both apps as untouched as possible, but enable one of them to
rule over the other.
sergiu uttered the idea of a REST approach, which i turned into some
kind of remote control for the xwiki user management.
so, whenever my forum admin want to have a new group, a new group is
created in both systems, a space with the id [groupname] is created
where only grup member have edit rights etc.
i attached an outline of that class.
that is, however, not the only way to do what you want, and possibly not
even the most appropriate.
Yours
Thomas

Hi
I have been thinking of integrating XWiki into a portal for sometime. The
ideal scenario would be to have a wiki, forum and blog all integrated within
the Portal, which is the company's knowledgebase.
Am debating whether to use SSO for different standalone apps like XWiki,
JForum etc or take a plunge into Exo/JBoss.
Any inputs/experiences would be greatly appreciated.
Thanks
Shiva

Thanks for the information. I think that like
Paul I'm going first to
install and use JForum (and give up phpBB), and then set it up so SSO is
used between both applications.

This response is probably not much use, but it might be, and besides I
enjoy showing off my brilliance...
Because JForum is a J2EE implementation of phpbb, moving to it will
probably be less difficult for users (and maybe administrators as well).
We
have installed JForum (and Roller for blogging) on the same appserver
with
our XWiki instance. The integration of the three was limited to placing
links to them in XWiki's viewheader menu. This has (I think) one small
advantage over phpbb since, as J2EE servlets, all could share the
appserver
and its session, so that logging in to one is logging in to all.
However, all three used separate user databases and hence separate
registration despite being on the same host and being skinned to look
mostly
like a single application. This resulted in a lot of user confusion,
because it was not clear that they needed to register individually on
each
of the three applications - I received numerous calls from users who
didn't
understand this.
If you use XWiki's LDAP plugin (and your forum tool has an equivalent
option) or a similar mechanism to what we are now doing - which is a
servlet
filter that digests cookies set by our SSO server and automatically
registers users in each one - this will all go much more smoothly, of
course.
The filter is simple to deploy but, with very little standardization in
J2EE security practices (none that I know of in the user lifecycle space)
it
can be challenging to adapt to each servlet's specific registration
needs.
In my case, the generic filter was finished in about three days (counting
the time it took to learn the relevant Servlet API parts) but the adapter
class that applied it to XWiki took more than two weeks. This was just a
little above the average: one JSP developer took my jarfile one morning
(while the filter was still in development), informed me of a bug around
noon, waited for me to fix the bug and deliver the new jarfile, and had
it
working with his app before he left for the day; the guy working with
Roller
took about three weeks (though, to be fair, he was also fighting the
vagaries of a new release of Roller with a very different configuration
of
the ACEGI security package). JForum took about the same as XWiki, mostly
because of having to interact with other servlet filters in its
deployment.

*Subject:* [xwiki-users] Which forum to use with XWiki
Hi,
With my XWiki I need a forum so people can exchange information on
various
topics. I'm installed phpbb but I was wondering if there was any "better"
integration between another product (JForum or JavaBB). Has anybody
installed such product ? Any feedback ?
Thanks,
Antonio
