/*
* ejabberd extauth script for the integration with friendica
*
* Originally written for joomla by Dalibor Karlovic <dado@krizevci.info>
* modified for Friendica by Michael Vogel <icarus@dabo.de>
* published under GPL
*
* Latest version of the original script for joomla is available at:
* http://87.230.15.86/~dado/ejabberd/joomla-login
*
* Installation:
*
* - Change it's owner to whichever user is running the server, ie. ejabberd
* $ chown ejabberd:ejabberd /path/to/friendica/include/auth_ejabberd.php
*
* - Change the access mode so it is readable only to the user ejabberd and has exec
* $ chmod 700 /path/to/friendica/include/auth_ejabberd.php
*
* - Edit your ejabberd.cfg file, comment out your auth_method and add:
* {auth_method, external}.
* {extauth_program, "/path/to/friendica/include/auth_ejabberd.php"}.
*
* - Restart your ejabberd service, you should be able to login with your friendica auth info
*
* Other hints:
* - if your users have a space or a @ in their nickname, they'll run into trouble
* registering with any client so they should be instructed to replace these chars
* " " (space) is replaced with "%20"
* "@" is replaced with "(a)"
*
