[imp] quota

[dhottinger@harrisonburg.k12.va.us]

I still havent gotten user quotas to work with horde 3.1.1, imp 4.1.3.  
  I have the following in my /imp/config/servers.php:
    'quota' => array(
     'driver' => 'command',
       'params' => array(
	'new_quota' => 'true',
          'quota_path' => '/usr/bin/quota',
           'grep_path'  => '/bin/grep'
       )
   ),
This is my imp/lib/quota/command.php:

class IMP_Quota_command extends IMP_Quota {

     /**
      * Constructor
      *
      * @access public
      *
      * @param optional array $params  Hash containing connection
parameters.
      */
     function IMP_Quota_command($params = array())
     {
         $this->_params = array(
             'quota_path' => 'quota',
             'grep_path'  => 'grep'
         );

         $this->_params = array_merge($this->_params, $params);
     }

     /**
      * Get quota information (used/allocated), in bytes.
      *
      * @access public
      *
      * @return mixed  An associative array.
      *                'limit' = Maximum quota allowed
      *                'usage' = Currently used portion of quota (in
bytes)
      *                Returns PEAR_Error on failure.
      */
     function getQuota()
     {
         global $imp;

         $imap_user = strtolower($imp['user']);
         $passwd_array = posix_getpwnam($imap_user);
         $homedir = split('/', $passwd_array['dir']);

             }

             exec($cmd, $cmd_output, $rc);

partition for

}
I dont get anything either in my httpd/error_logs, nor do I get any  
php warnings with error_display turned on.  I dont have anything in my  
top menu.  Nothing in my horde portal blocks.  Quotas are enabled for  
/dev/sdb.  quota command returns each users quota.  I added Cmnd_Alias  
QUOTA = /usr/bin/quota
apache  ALL= (ALL)NOPASSWD: QUOTA
to my /etc/sudoers.  Does anyone have this working?  Im running an fc  
6.  If you do can you send me a screen shot or help me get it going?   
I have 750 users and definately need quotas for the users.

thanks,

ddh
