OpenID for dummies?

I'm thinking about adding an openid widget to a toolkit I'm developing.

An important part of that is keeping the UI as simple as possible - although there's lots of openid tools available they mostly rely on providing a text input box to enter a URL - however as demonstrated here on SO - there are a lot of openID providers which use a generic URL as the endpoint - so it's simply a matter of clicking on a button/开发者_如何学Pythonimage. I want to provide this service. Indeed, I want to provide the facility to restrict the providers to an approved list.

(I've got openIds from various providers - but do not have a clue what the URLs are - that doesn't prevent me from using sites like this which provide clickable sign-ins!)

Unfortunately Valdimir's openid class, Janrains PHP OpenID libs, Dope OpenId, and LightOpenId just provide the text box.

Is there a directory of openID provider URLs anywhere? With redistributable graphics?

I did find IDselector.com (where you need an OpenId to access most of the site - but they do not implement their widget on their own site!!!!) but its not very clear what the licensing is.

Are there other/newer libs I should be aware of? This S.O. post is nearly 3 years old!

Some more selectors:

• http://code.google.com/p/openid-ps/
• http://code.google.com/p/open-selector/
• http://code.google.com/p/openid-selector/
• http://code.google.com/p/openid-realselector/

My personal favorite is openid-realselector (demo).

The open-id-selector project provides a jQuery-based method of generating a simple form for selecting an Open ID providor. It comes with several common OpenID providors and the appropriate icons.

See a non-functional demo here.

Note that this is only part of the solution; you must still implement OpenID authentication on the server-side, as well, and configure open-id-selector to leverage it (by directing the form to the appropriate path).

Integrate WebFinger, so you just have to offer an email input field.
