I have several complaints that users cannot contribute to my ikiwiki instances since they only have OpenID logins that support OpenID2. E.g. Yahoo!'s OpenID only supports 2.0+
This is not the fault of ikiwiki, though the problem lies within the perl openid consumer in Debian which is a 1.x implementation AFAIK.
I've contacted JanRain who have pointed me to:
However both Perl OpenID 2.x implementations have not been released and are incomplete implementations.
Both of the projects referenced above have since been released. Net::OpenID::Consumer 0.x in Debian is indeed only an OpenID 1 implementation. However, Net::OpenID::Consumer 1.x claims to be an OpenID 2 implementation (it's the second of the projects above). I've filed a bug in Debian asking for the package to be updated. --smcv
Net::OpenID::Consumer 1.x is now in Debian unstable --dom
