I am a complete n00b to configuring Jabber/XMPP servers and I am hoping to get some help getting set up. I have done all of [this](https://help.ubuntu.com/community/SettingUpJabberServer) and installed [pidgin](http://www.pidgin.im/). I seem to be able set up my "admin-user" in pidgin no problem but when I try to register a new user I get a 403 Fobidden message back from pidgin.

Do I need to change the ejabberd.cfg file to allow users to register? If so how do I go about it? If not what do I need to get basic chat and fileshare going?
