+      "Custom scripts" module to all needed account types on the configuration
+      pages.</para>
+
+      <para>You can specify multiple scripts for each action type (e.g.
+      modify) and account type (e.g. user). The scripts need to be located on
+      the filesystem of your webserver and will be executed in its user
+      environment. E.g. if you webserver runs as user www-data with the group
+      www-data then the custom scripts will be run under this user with his
