i need a complete procedure on how to setup Oauth 2.0 authentification between my own IBM/Notes/Domino/XPages apps and my own Connections 4.5 server (no greenhouse or quick start connections over the web)

Have installed both are on the same machine same host name with different ports :
Connections 4.5 (HTTP 80/HTTPS 443)
Running secure mode ok
Domino 9 (HTTP 8088/ HTTPS 44388)
Accessing Connections in SSL works fine.
Runnig XPages SSL/Domino with specific ports too.

Follow the IBM SBT docs : 

<http://www-10.lotus.com/ldd/lcwiki.nsf/xpDocViewer.xsp?lookupName=IBM+Connections+4.5+Documentation#action=openDocument&res_title=Registering_an_OAuth_client_with_a_provider_ic45&content=pdcontent>

Create a credential on the WAS 8.0.0.6 :

<http://www-10.lotus.com/ldd/lcwiki.nsf/xpDocViewer.xsp?lookupName=IBM+Connections+4.5+Documentation#action=openDocument&res_title=Managing_the_client_application_list_ic45&content=pdcontent>

but have question about the redirecturi to specify when creating credentials ? {opensocialSvcUrl}/gadgets/oauth2callback" stated is for gadget only no ?

Question is how to create correct credential in websphere and how to configure it in the SBTPayground.nsf Lotus application (Open NTF) to succesfully log in via OAuth2.0 (only basic authentication works...)

Thanks for any help.
