+LDAP Support
+============
+
+It is possible to manage mail user accounts with LDAP rather than with
+the option `loginAccounts <options.html#mailserver-loginaccounts>`_.
+
+All related LDAP options are described in the `LDAP options section
+<options.html#mailserver-ldap>`_ and the `LDAP test
+<https://gitlab.com/simple-nixos-mailserver/nixos-mailserver/-/blob/master/tests/ldap.nix>`_
+provides a getting started example.
+
+.. note::
+   The LDAP support can not be enabled if some accounts are also defined with ``mailserver.loginAccounts``.
