How can i use this with openid?

[Stephan Richter]

http://extensions.joomla.org/extensions/access-a-security/site-access/authentication-cloud-based/5366 states, that this plugin can be used to allow logins via openid. I can't find any documentation on how to establish this. Could you please help me?

This is not implemented. But the framework can use any external authentication. See the CAS plugin as an example
