Editing OpenID (section)

== How ==
* First do some experiments with the CS Wiki
** Evan from Wikivoyage wrote some patches for MediaWiki: http://www.nabble.com/OpenID-extension-for-MediaWiki-t1999721.html
* There are many libraries at http://openid.net/wiki/index.php/Libraries
* According to the [http://www.openidenabled.com/openid/openid-protocol OpenId protocol], CouchSurfing could act as consumer, as server or as both.
: An OpenId consumer (or Relying Party)  is a web site (server) that allows users to login using an OpenId URL (for example, http://zooomr.com allows users to log in with openid urls).
: An OpenId server (or OpenID Provider or Identity Provider) is a server that gives registered users an OpenId URL, with this OpenID URL users can then login in other web sites (for example, every user  of [http://livejournal.org livejournal] can use <nowiki>http://<username>.livejournal.org</nowiki> as OpenId URL and so can use this OpenId URL in order to login in other sites).
: CouchSurfing could act both as consumer and as server:
:: it seems reasonable to first deploy an OpenId consumer, so that CSers can log in using their already existant OpenId urls.
:: as a second step, we could deploy an OpenId server, so that CSers can use <nowiki>http://<username>.couchsurfing.com</nowiki> as their OpenId URL, this means it will be the site they visit and log into every morning. Then they will never ever to login in different sites with ad hoc logins and passwords.
