Sven Dowideit’s working on re-architecting TWiki’s authentication and session system to enable better support for external user management – for the upcoming TWiki 4.2.0 release in June, we should see OpenID support – at least for login, and registration – and later, TWiki will be able to be an OpenID providor too..
To make the June – July release, we’re expecting to re-release the Jan-Rain CPAN Consumer – to fix bugs, and make taint safe, and then depending on demand and support, to either maintain that library as the premier perl OpenID library, or when the SXIP library becomes a reality, to port to that.
I guess our thunder has been stolen by Sun’s rather big announcement – http://blogs.sun.com/superpat/entry/openid_at_sun … but it does make the work more important, as Sun use TWiki for things like http://wiki.java.net
