As an experiment, I picked the New Sites category and attempted to use my ProtectNetwork.org OpenID. Here are the results:
- http://www.fileformat.info/ - no option to log-in (using OpenID or otherwise)
- http://health20.org/ - Received 'The server encountered an internal error () that prevented it from fulfilling this request' after authenticating to my IDP. Interestingly, the site used the LID GUI model (i.e. icon in bottom right corner).
- http://www.phixr.com/photo/ - unable to login, the site indicates you can supply either a user name or OpenID, but still demands a password
- http://www.sylvainbriant.com - no option to log-in (using OpenID or otherwise)
- http://www.suppressionlist.com/ - Received 'Application error' after authenticating to IDP
- http://www.placeengine.com - No option to log-in (using OpenID or otherwise)
- http://www.insanejournal.com/ - Success!
- http://www.donengel.net/ - Partial Success. After successfully being redirected to my IDP, I consented to the release of my email back to the SP. Nonetheless, the SP still asked me for my email.
- http://www.challgren.com/ - Success
- http://www.finnix.org - Success
Separately, there were almost as many 'ceremonies' as there were sites. Permutations included:
- offering OpenID login as a peer to normal local account (e.g. Doxory)
- linking from main log-in page to an OpenID specific page (e.g. Finnix.org)
- variations on 'LogIn', 'Verify', as the etc (e.g. Challgren.com)
- Asking for an OpenID AND a password (e.g. Phixr)
- Describing the OpenID option as 'Blog URL' (e.g. Challgren.com)
