+# Configuring Ejabberd (XMPP Server) to use Pleroma for authentication
+
+If you want to give your Pleroma users an XMPP (chat) account, you can configure [Ejabberd](https://github.com/processone/ejabberd) to use your Pleroma server for user authentication, automatically giving every local user an XMPP account.
+
+In general, you just have to follow the configuration described at [https://docs.ejabberd.im/admin/configuration/authentication/#external-script](https://docs.ejabberd.im/admin/configuration/authentication/#external-script). Please read this section carefully. 
+
+Copy the script below to suitable path on your system and set owner and permissions. Also do not forget adjusting `PLEROMA_HOST` and `PLEROMA_PORT`, if necessary.
+
+```bash
+cp pleroma_ejabberd_auth.py /etc/ejabberd/pleroma_ejabberd_auth.py
+chown ejabberd /etc/ejabberd/pleroma_ejabberd_auth.py
+chmod 700 /etc/ejabberd/pleroma_ejabberd_auth.py
+```
+
+Set external auth params in ejabberd.yaml file:
+
+```bash
+auth_method: [external]
+extauth_program: "python3 /etc/ejabberd/pleroma_ejabberd_auth.py"
+extauth_instances: 3
+auth_use_cache: false
+```
+
+Restart / reload your ejabberd service.
+
+After restarting your Ejabberd server, your users should now be able to connect with their Pleroma credentials.
