I'm developing TAI for OpenID Connect purpose. So, I want that user auth in My main mission: on main page of WebSphere Portal (WSP), user press button "Login using Google" (Google just for an example of OpenID Connect Auth), than user redirecting to page, where he is write his credentials of service, next service redirects him to my WSP again where he would be auth success.
I asked about technology (mechanism of WAS) which let me implement this scenario in WebSphere Application Server (WAS) and WebSphere Portal (WSP), the answer is TAI. Now I can't understand how I can redirect user in TAI to specific page and waiting for response. If I wrong with mechanism, please tell me how I can implement it.
