Scratchpad for howto on xwiki.org

Vincent, Sergiu, and the whole community: My conversation begun by Gunther Leeb has continued offline and I've agreed to help him implement a solution similar to one I've created, which will probably be generally useful. Ironically enough, we seem to have validated the old adage of the cobbler's children going barefoot - we're working on a feature of a Wiki, and though we have a community of interested users and developers and access to a Wiki, we began by still using a one-to-one email exchange. In repentance thereof, I wish to nail down a page or three on xwiki.org to simultaneously develop, publish, and offer for comment the work we are doing. Where would be the best place to put this? The topic is enhancing the LDAP authentication service implementation in the ways that Gunter needs, which would add a feature to discriminate on values in the LDAP-supplied user information. brain[sic]
