+Configuration
+-------------
+
+| Orchestrator requires a one file to be configured properly.
+
+Configuration file
+""""""""""""""""""
+.. note::
+ The editable file is located at **/etc/fusiondirectory-orchestrator/orchestrator.conf**
+
+[LDAP settings]
+^^^^^^^^^^^^^^^
+.. code-block:: shell
+
+ LDAP_HOST="localhost"
+
+Required in order to connect to the proper host.
+FQDN or IP must be provided.
+
+.. code-block:: shell
+
+ LDAP_ADMIN="cn=admin,dc=fusiondirectory,dc=org"
+
+Required by LDAP in order to use the proper privileges.

+.. code-block:: shell
+
+ LDAP_PWD="ldap_pwd"
+
+Required password to authenticate LDAP
+
+.. code-block:: shell
+
+ LDAP_OU_USER="ou=people,dc=fusiondirectory"
+
+Required to ease the research of the branch people by endpoints.
+
+[JWT token settings]
+^^^^^^^^^^^^^^^^^^^^
+
+.. code-block:: shell
+
+ #SECRET_KEY can be generated via a 256 bit Wep key generator such as
+ #https://allkeysgenerator.com/
+ SECRET_KEY="256 bit key"
+
+Required to secure and validate the generation of access and refresh tokens.
+
+[SMTP server settings]
+^^^^^^^^^^^^^^^^^^^^^^
+.. code-block:: shell
+
+ MAIL_USER="mail_user"
+
+The login ID to authenticate to the specified SMTP server.
+
+.. code-block:: shell
+
+ MAIL_PASS="mail_pwd"
+
+The password used for above authentication.
+
+.. code-block:: shell
+
+ MAIL_HOST="fqdn or IP"
+
+The SMTP server domain name or IP.
+
+.. code-block:: shell
+

+
+ MAIL_PORT="SMTP port number"
+
+The TCP/UDP port number of the SMTP server.(Example: SSL 465 / TLS 586).
+
+.. Note::
+
+ | Orchestrator is highly depending on the URL rewriting mechanism of the web server.
+ | In case of Apache2 ".htaccess" files are responsible for that logic.
+
+ | Although informative, there should not be any value of modifying the contents of those files.
+ | The goal is to redirect any call on URI to the main index file located in API directory.

+- Schedule for the tasks.
+- A max-emails threshold to be sent.
+- A time interval between mail tasks processing.
+
+.. note::
+ The settings for above conditions are found within FusionDirectory configuration menu.
