Open id provider and hybridauth

I'm trying to use drupal website with open id provider module as another login source for http://drupal.org/project/hybridauth
Here is the way I'm trying it to integrate: http://drupal.org/node/1889012

It requires to provide the url of endpoint for login.
I've tried something like:

var $openidIdentifier = "http://[my website with openid]/openid";

but when trying to login using this plugin it just leads browser to endless loop.
Is it me doing something wrong?
Thanks in advance.
