How to register a new user in ejabberd

Question

From egoscia's answer on the question Register a new user in ejabberd using Erlang , he says in the accepted answer that you can add a new user using:

ejabberd_auth:try_register(<<"username">>, <<"example.com">>, <<"secret_password">>).  

I tried using this in erlang, but I get the error:

** exception error: undefined function ejabberd_auth:try_register/3  

This is a snippet of how I go about it:

-import(ejabberd_auth, [try_register/3]).

start() ->
  io:fwrite("Hello World!\nThis is Sound\n"),

  % Chat
  ejabberd_auth:try_register(<<"username">>, <<"example.com">>, <<"secret_password">>).  

How should I go about it erlang? Java/ Android/ C++/ Qt suggestions also welcome.

Thank you all in advance.

Oh, that code works for me using ejabberd 18.03. I start ejabberd in live mode, so I have access to the erlang shell, and I can run correctly:

$ ejabberdctl live
...
(ejabberd@localhost)2> ejabberd_auth:try_register(<<"user6">>, <<"localhost">>, <<"somepass">>).
ok

Maybe you are using an old ejabberd version that doesn't still export ejabberd_auth:try_register/3 ?
