[Ejabberd](https://www.ejabberd.im/) is a chat server that uses XMPP as messaging protocol that you can use with a large amount of clients. In conjunction with the “xmpp” addon it can be used for a web based chat solution for your users.

Installation

- Change it's owner to whichever user is running the server, ie. ejabberd

      $ chown ejabberd:ejabberd /path/to/friendica/bin/auth_ejabberd.php

- Change the access mode so it is readable only to the user ejabberd and has exec

      $ chmod 700 /path/to/friendica/bin/auth_ejabberd.php

- Edit your ejabberd.cfg file, comment out your auth_method and add:

      {auth_method, external}.
      {extauth_program, "/path/to/friendica/bin/auth_ejabberd.php"}.

- Disable the module “mod_register” and disable the registration:

      {access, register, [{deny, all}]}.

- Enable BOSH:

1. Enable the module “mod_http_bind”
2. Edit this line:

      {5280, ejabberd_http,    [captcha, http_poll, http_bind]}

1. In your apache configuration for your site add this line:

      ProxyPass /http-bind http://127.0.0.1:5280/http-bind retry=0

- Restart your ejabberd service, you should be able to login with your friendica credentials

Other hints

- if a user has a space or a @ in the nickname, the user has to replace these characters:

1. “ ” (space) is replaced with “%20”
2. “@” is replaced with “(a)”
