[imp] Menu buttons in horde/imp modules

[Krishna]

Hi,
       I made a change to set passwd,forward and vacation options in the 
IMP options page.
This is how I did in /imp/config/prefs.php

$prefGroups['passwd'] = array(
     'column' => _("Your Information"),
     'label' => _("Password"),
     'desc' => _("Change your password"),
     'url' => '/horde/passwd/index.php');

$prefGroups['forwards'] = array(
     'column' => _("Your Information"),
     'label' => _("Mail Forwarding"),
     'desc' => _("Set your mail forwarded to another account"),
     'url' => '/horde/forwards/index.php');

$prefGroups['vacation'] = array(
     'column' => _("Your Information"),
     'label' => _("Vacation"),
     'desc' => _("Set a vacation auto-responder"),
     'url' => '/horde/vacation/index.php');

They work alright, but I couldn't get the menu buttons of IMP/Mail !!
How can I put them on these pages of forward,passwdand vacation???

Usingrde/IMP cvs version.
OS: RedHat 7.3
Modules: All cvs version's.
