pushing stream to other evoserver using username:password

Hi, I have setup one server to receive streams with user/password autentication. and works fine pushing streams from my transcoders. but now I like to push this streams from this server to an other evoserver. this server is also using username/password. for incomming streams. How am I doing this as "pushStream uri=rtmp://user:password@serveraddres/live/streamname localStreamName=myStreamName" is not working. nor is "pushStream uri=rtmp://user:password@serveraddres localStreamName=myStreamName" is not working. rtsp is working but i like to do this with rtmp. kind regards Marc.
