I am trying to use openldap for rabbitmq auth. But when monitoring openldap log, it always has error information.
It is planed to insert debug code into rabbitmq's source code by replacing the ebin file.
Two question:
how to make rabbitmq-server started with shell input, so it is possible to debug online. By default ps -ef show rabbitmq start with
noshell. How to change it?yus-iMac:ebin yuchen$ ps -ef|grep erl

I have checked the boot script "rabbitmq-server"
exec ${ERL_DIR}erl \
-pa ${RABBITMQ_EBIN_ROOT} \

Add the following debug code.
echo "erl dir:" ${ERL_DIR}
echo "pa:" ${RABBITMQ_EBIN_ROOT}
echo "ebin_root:" ${RABBITMQ_EBIN_ROOT}
echo "boot:" ${SASL_BOOT_FILE}

echo "config_args:" ${RABBITMQ_CONFIG_ARG}
echo "server_erl_args:" ${RABBITMQ_SERVER_ERL_ARGS}
echo "listen_arg:" ${RABBITMQ_LISTEN_ARG}
The debug result is as following:
erl dir: /usr/local/Cellar/rabbitmq/3.1.5/erts-5.10.2/bin/
pa: /usr/local/Cellar/rabbitmq/3.1.5/ebin
ebin_root: /usr/local/Cellar/rabbitmq/3.1.5/ebin

listen_arg: -rabbit tcp_listeners [{"127.0.0.1",5672}]
There is only 'no input',but not exists "noshell", where ps -ef 's output noshell comes from?
I have replaced the "rabbit_auth_backend_ldap.beam" with new one. But after restart rabbitmq-server, and connect it, but the debugging information is not in the rabbitmq log. It seems that my new one is not work.
yus-iMac:ebin yuchen$ pwd /usr/local/Cellar/rabbitmq/3.1.5/plugins/expand/rabbitmq_auth_backend_ldap-3.1.5/ebin

The changed file partly code as follows, I have added 111 after template:
log(_Fmt, _Args, #state{log = false}) -> ok;
log( Fmt, Args, _State) -> rabbit_log:info(Fmt ++ "~n", Args).
fill(Fmt, Args, State) ->
?L2("filling template111 \"~s\" with~n ~p", [Fmt, Args], State),
R = rabbit_auth_backend_ldap_util:fill(Fmt, Args),
?L2("template result: \"~s\"", [R], State),
R.
The log no change after rabbitmq-server's restart.
