I don't know how to setup the outh module right. I found also the question How do I configure the Services OAuth sub-module? but that answer is very old and ends with a "To be continued..." statement.
So far I get out that I need to generate a context (http://example.org/admin/config/services/oauth/contexts) and a oauth connector (http://example.org/admin/structure/oauthconnector). So I think I setted them correctly but I cannot see where the user may access that.
Could you point me to a tutorial or something like that? I'm not able to find the right words to google that myself. Sorry for that!
