File_Passwd and shadow passwords

Can anyone tell me if File_Passwd can work with shadow password files?

The following snippet of code is allowing alterations to the /etc/passwd
file, and an "x" is inserted into the password field (which is
expected). Shadow remains untouched...

include_once('File/Passwd.php');

$passwd = &File_Passwd::factory('Unix');
$passwd->setFile('/etc/passwd');
$passwd->useMap(true);
$passwd->load();
$extra = array('pass'=>'testpass', 'home'=>'/home/testuser',
'gecos'=>'Added by script...', 'shell'=>'/bin/bash');
$passwd->addUser('testuser', 'testpass', $extra);
$passwd->save();

I've been through the docs, and all I can see is that a PEAR_Error is
thrown when a shadow password configuration is detected. Does this
simply mean it doesn't have that capability? Google is rather dry on
relevant information too.

Thanks,

Sorry for the late answer, but I'm currently lacking time.

This question has been asked some time ago, please search the
archive for a wrapper function; it basically creates two
File_Passwd_Unix objects, one for /etc/passwd and one for
/etc/shadow. Please note that you must not specify the password in
the "extra" fields and that you need to define the extra fields map
for the shadow file manually.
