[Freeswitch-users] event socket : userauth undocumented esl command?

Hi, I''ve read in an old esl source that a userauth command exist in mod_event_socket and provides user/password based authentication, not only password based, like auth... Th actual code accepts the userauth command... Question: where can I configure the user / password for the userauth command? Shouldn't this command bee in wiki? Thanks, John
