You want STOZE to use the authentication from TIKSN? Well, you have to configure STOZE as an "oAuth resource server", so it keeps the protected resources, and configured to work only with token he gets from TIKSN, which will be configured as an "oAuth identity provider".

OpenID is a different story - then, you will have to configure TIKSN as "OpenID provider", and configure STOZE to enable it to work with OpenID providers (so TIKSN will be one of them, but you will be able to use also Google, Yahoo, etc)
