wp-yadis is a Wordpress plug-in to aid in delegating your OpenID to another server. (Read more here). This plugin was formally called ‘wp-xrds’ so you may still see that name in a few places.
Installation & Usage
Simply drop the file into your plugins folder, activate it, and go configure it in the “Options” window. You can maintain multiple servers, so that if one fails, applications should fail over to one of your other ones. The plug-in will generate openid.server and openid.delegate link tags in your site header as well as automatically generate a full Yadis document on the fly.

To-Do
There are a few more things I’d like to add, but just haven’t had the time as of yet. My current wish-list includes (in no particular order):
- look at supporting other XRDS based providers (not just OpenID)
- more pre-defined providers
- various code cleanup
If you spot something that’s not on the list, please let me know.
