+---
+
+There are two ways to integrate *Authelia* with an authentication backend:
+
+* [LDAP](ldap.md): users are stored in remote servers like [OpenLDAP], [OpenDJ], [FreeIPA], or
+  [Microsoft Active Directory].
+* [File](file.md): users are stored in [YAML] file with a hashed version of their password.
+
+## Configuration
+
+```yaml
+authentication_backend:
+  refresh_interval: 5m
+  disable_reset_password: false
+  password_reset:
+    custom_url: ""
+```
+
+## Options
+
+### refresh_interval
+
+{{< confkey type="duration" default="5m" required="no" >}}
+
+This setting controls the interval at which details are refreshed from the backend. Particularly useful for
+[LDAP](#ldap).
+
+### disable_reset_password
+
+{{< confkey type="boolean" default="false" required="no" >}}
+
+This setting controls if users can reset their password from the web frontend or not.
+
+### password_reset
+
+#### custom_url
+
+{{< confkey type="string" required="no" >}}
+
+The custom password reset URL. This replaces the inbuilt password reset functionality and disables the endpoints if
+this is configured to anything other than nothing or an empty string.
+
