SSOCircle

SSOCircle the first Identity Provider supporting SAML 2.0 and OpenID protocols now includes attribute exchange through OpenID Simple Registration Extension.
You are now able to share profile attributes ( like name or email address ) between the IDP and the Relying Party. You will be asked to confirm the transfer of attributes as soon as the service you are signing in is asking for it.
Thanks to Paul C. Bryan for making this possible.
