[App_rpt-users] Echolink Unauthorized

Is there anything specific that needs to be configured to permit certain connections to the repeater via echolink? Specifically, when attempting to connect as user X to X-R (repeater), the client returns "Un-authorized". The echolink.conf file has no permit/deny parameters, so by default all connections should be accepted? Hopefully this hasn't been asked elsewhere, if so, please direct me to that thread; otherwise, any pointers appreciated. 73 - Eric - NO3M
