+*Python LDAP Applications* articles by Matt Butcher
+---------------------------------------------------
+
+* `Part 1 - Installing and Configuring the Python-LDAP Library and Binding to an LDAP Directory <https://www.packtpub.com/article/installing-and-configuring-the-python-ldap-library-and-binding-to-an-ldap-directory>`_
+
+    This also covers SASL.
+
+* `Part 2 - LDAP Operations <https://www.packtpub.com/article/python-ldap-applications-ldap-opearations>`_
+* `Part 3 - More LDAP Operations and the LDAP URL Library <https://www.packtpub.com/article/python-ldap-applications-more-ldap-operations-and-the-ldap-url-library>`_
+* `Part 4 - LDAP Schema <https://www.packtpub.com/article/python-ldap-applications-ldap-schema>`_
+
+    Gee, someone waded through the badly documented mysteries of module
+    :mod:`ldap.schema`.
+
+
+`LDAP Programming in Python <https://www.linuxjournal.com/article/6988>`_
+-------------------------------------------------------------------------
+
+Another article for getting started with python-ldap.
+
+
+
+`RFC 1823 <https://tools.ietf.org/html/rfc1823>`_
+-------------------------------------------------
+
+The LDAP Application Program Interface, mainly for LDAPv2.
+
+
+
+`LDAPEXT draft <https://tools.ietf.org/html/draft-ietf-ldapext-ldap-c-api>`_
+----------------------------------------------------------------------------
+
+The Internet draft of the discontinued IETF working group LDAPEXT is of
+interest here since the OpenLDAP 2 libs implement this (expired) draft.
+
+
+`OpenLDAP <https://www.openldap.org/>`_
+---------------------------------------
+
+It's worth to have a look at the
+`manual pages <https://www.openldap.org/software/man.cgi?query=ldap>`_ and the
+`Developer's FAQ <https://www.openldap.org/faq/data/cache/4.html>`_.
+
+
+`VSLDAP <https://www.opengroup.org/openbrand/testing/checklist/guide/config_base.html>`_
