Is OAuth broken?

[eloo]

I've tested the OAuth mechanism but it seems the implementation is broken.

After a while of testing i got it work with the following changes to xmpp.go

                  if m == "X-HIPCHAT-OAUTH2" && o.OAuthToken != ""  {
                        mechanism = m
                        // Oauth authentication: send base64-encoded \x00 token \x00 resource.
                        raw := "\x00" + o.OAuthToken + "\x00" + o.Resource
                        enc := make([]byte, base64.StdEncoding.EncodedLen(len(raw)))
                        base64.StdEncoding.Encode(enc, []byte(raw))
                        outString := fmt.Sprintf("<auth xmlns='http://hipchat.com' node='http://hipchat.com/client/mac' ver='22' mechanism='oauth2'>%s</auth>", enc)
                        fmt.Println(outString)
                        fmt.Fprint(c.conn, outString)
                        break
                  }
                  if m == "PLAIN" && o.Password != "" {
                        mechanism = m
                        // Plain authentication: send base64-encoded \x00 user \x00 password.
                        raw := "\x00" + user + "\x00" + o.Password
                        enc := make([]byte, base64.StdEncoding.EncodedLen(len(raw)))
                        base64.StdEncoding.Encode(enc, []byte(raw))
                        fmt.Fprintf(c.conn, "<auth xmlns='%s' mechanism='PLAIN'>%s</auth>\n", nsSASL, enc)
                        break
                  }

now i'm receiving the following output

<success xmlns='urn:ietf:params:xml:ns:xmpp-sasl' jid='<jid_number>@chat.btf.hipchat.com/bot||proxy|<myHost>|<number>' api_host='<myHost>' chat_host='chat.btf.hipchat.com' muc_host='conf.btf.hipchat.com' web_host='<myHost>'/>

but the client throws still an error

another implementation of the oauth could be found here

is anyone using oauth in xmpp?
