Yes. It leads to the error: "Backend Configuration Error: Home 
directory not below root."

Emre.

Did you try root = '~' and home = ''? home = './' doesn't look correct to me.

Hi,

If you have multiple home directories on the ftp server like;

/home_1/user_a
/home_2/user_b

you cannot define a static 'root' => '/home' and a 'home' => 
Auth::getAuth() line to jail a user to the home (in conf/backends.php).

The only choice left (that I could figure out :) is to use something 
like 'root' => '~' and 'home' => './' which seems to be working until 
you try to "cd" to a sub-directory (error: ~/~/sub-directory not found).

This did the trick for me;

Added the lines below to horde/gollem/lib/Sessions.php just above the comment:
"Make sure the home parameter lives under root ...." on line 127;

if (!empty($ptr['multihomejail'])) {
      if ($ptr['multihomejail'] == true) {
          $ptr['home'] =  $GLOBALS['gollem_vfs']->getCurrentDirectory();
          $ptr['root'] =  $ptr['home'];
      }
  }

and added the parameter 'multihomejail' => true to 
horde/gollem/config/backends.php . A sample ftp entry looks like this;

$backends['hordeftp'] = array(
     'name' => 'WebFTP',
     'driver' => 'ftp',
     'preferred' => '',
     'hordeauth' => true,
     'params' => array(
         'hostspec' => 'servername',
         'port' => 21,
         'pasv' => true,
         'vfsroot' => '',
        'permissions' => '700'
     ),
     'loginparams' => array(
     ),
     'root' => '',
     'home' => '',
     'multihomejail' => true,
     'clipboard' => true,
     'attributes' => array('type', 'name', 'edit', 'download', 
'modified', 'size', 'permission', 'owner', 'group')
);
