+    When set, this points to an alternate database host used for storing the ":ref:`linked-tables`" database.
+
+    .. seealso:: :config:option:`$cfg['Servers'][$i]['controlhost']`
+
+.. envvar:: PMA_CONTROLUSER
+
+    Defines the username for phpMyAdmin to use for the ":ref:`linked-tables`" database.

+.. envvar:: PMA_PMADB
+
+    When set, define the name of the database to be used for the ":ref:`linked-tables`" database.
+    When not set, the advanced features are not enabled by default: they can still potentially be enabled by the user when logging in with the :ref:`zeroconf` feature.

+
+    .. seealso:: :config:option:`$cfg['Servers'][$i]['pmadb']`

     If defined, this option will hide the PHP version (`expose_php = Off`).
