[sork] Horde H3 Passwd & vpopmail

[Sergej Pisarenko]

I am using Horde H3 on qmail,vpopmail,apache2.0,php5 environment.
Horde works as it should but I have problems with using passwd module
for changing e-mail password.

This is my backends.php:
==================
  $backends['vpopmail'] = array (
      'name' => 'Vpopmail',
      'preferred' => '',
      'password policy' => array(
          'minLength' => 4,
          'maxLength' => 32,
          'maxSpace' => 2,
          'minUpper' => 0,
          'minLower' => 0,
          'minNumeric' => 0
      ),
      'driver' => 'vpopmail',
      'params' => array(
          'phptype'    => 'mysqli',
          'hostspec'   => 'localhost',
          'username'   => 'vpopmail',
          'password'   => 'my_pass',
          'encryption' => 'crypt-md5',
          'database'   => 'vpopmail',
          'table'      => 'vpopmail',
          'name'    => 'pw_name',
          'domain'  => 'pw_domain',
          'passwd' =>  'pw_passwd',
          'clear_passwd' => 'pw_clear_passwd',
          'use_clear_passwd' => true,
          'show_encryption' => true
      )
  );
==================
I use vpopmail with clear_passwd flag.

My passwd/conf.php:
==================
  <?php
  /* CONFIG START. DO NOT CHANGE ANYTHING IN OR AFTER THIS LINE. */
  // $Horde: passwd/config/conf.xml,v 1.12 2005/10/09 14:48:58 jan Exp $
  $conf['menu']['apps'] = array('horde', 'imp', 'passwd', 'turba');
  $conf['backend']['backend_list'] = 'shown';
  $conf['user']['change'] = false;
  $conf['user']['refused'] = array('root', 'bin', 'daemon', 'adm', 'lp', 'shutdown', 'halt', 'uucp', 'ftp', 'anonymous', 'nobody', 'httpd', 'operator', 'guest$
  $conf['password']['strengthtests'] = true;
  $conf['hooks']['full_name'] = true;
  $conf['hooks']['default_username'] = false;
  $conf['hooks']['username'] = false;
  $conf['hooks']['userdn'] = false;
  /* CONFIG END. DO NOT CHANGE ANYTHING IN OR BEFORE THIS LINE. */
==================

I set it up in horde setup but when I try to actually change password
blank screen appears and password does not change.

What can be wrong? Where can I see the logs? How to track down
errors?

I use vpopmail-5.4.6-r1


Best regards, Sergej.
