+# AnsibleWorks AWX can be configured to centrally use LDAP as a source for
+# authentication information.  When so configured, a user who logs in with
+# a LDAP username and password will automatically get an AWX account created
+# for them, and they can be automatically placed into multiple organizations
+# as either regular users or organization administrators.  If users are created
+# via an LDAP login, by default they cannot change their username, firstname,
+# lastname, or set a local password for themselves. This is also tunable
+# to restrict editing of other field names.
+
+# For more information about these various settings, advanced users may refer
+# to django-auth-ldap docs, though this should not be neccessary for most
+# users: http://pythonhosted.org/django-auth-ldap/authentication.html
