Unable to use ejabberdctl :\

Hello,

I'm very sorry for this question that must be kinda stupid, but I can't seem to find how to use ejabberdctl...

I installed the package ejabberd on Debian, I modified the config file, but when I try and use ejabberdctl I get an error, for the program can't be found. And I couldn't find it anywhere :\

What should I do in order to add the admin account, necessary to log in the web interface ?

Thank you

edit : Sorry, I found it in /usr/sbin, which is not considered in my PATH
