+
+Here is an example of the use of _prefs_change_hook_
+
+We are using a CAS SSO as an Auth Method. So we don't have any horde  
login page. So what?. Remember that in the login page, you can select  
which mail frontend you want to use and also get rid of sidebar if  
dimp is selected. It tooks time to understand how to do that.  
post_authenticate can't do the job as user prefs are not loaded.
+
+So:
+We have to  leave show_sidebar unlock, but people can't modify. To do  
that, we don't display the value in prefs.php
+<code type=php>
+$prefGroups['display'] = array(
+    'column' => _("Other Information"),
+    'label' => _("Display Options"),
+    'desc' => _("Set your startup application, color scheme, page  
refreshing, and other display options."),
+    'members' => array('initial_application', 'show_last_login', 'theme',
+                     #  'summary_refresh_time', 'show_sidebar',  
'sidebar_width', # DOM
+                       'summary_refresh_time',  'sidebar_width',
+                       'moz_sidebar', 'menu_view', 'menu_refresh_time',
+                       'widget_accesskey')
+);
+</code>
+
+To select dimp, we need a change in registry.php
+
+<code type=php>
+$this->applications['dimp'] = array(
+    'fileroot' => dirname(__FILE__) . '/../dimp',
+    'webroot' => $this->applications['horde']['webroot'] . '/dimp',
+    'name' => _("Dynamic Mail"),
+    'status' => 'active',
+    'target' => '_parent',
+);
+<code>
+
+And then, the change hook:
+
+<code type=php>
+if (!function_exists('_prefs_change_hook_initial_application')) {
+     function _prefs_change_hook_initial_application()
+     {
+         $initapp=$GLOBALS['prefs']->getValue('initial_application');
+         if (strcmp($initapp,'dimp')==0){
+            $GLOBALS['prefs']->setValue('show_sidebar',false);
+         }
+         else {
+            $GLOBALS['prefs']->setValue('show_sidebar',true);
+         }
+     }
+}
+</code>
