Install an ejabberd with synchronized credentials
=================================================
* [Home](help)
[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/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"}.
- Disable the module "mod_register" and disable the registration:
{access, register, [{deny, all}]}.
- Enable BOSH:
- Enable the module "mod_http_bind"
- Edit this line:
{5280, ejabberd_http, [captcha, http_poll, http_bind]}
- 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:
- " " (space) is replaced with "%20"
- "@" is replaced with "(a)"
