Change password from the webmail OSX 10.4.5 - INSTRUCTIONS

Question

Working with OSX 10.4.5
This instruction is based on hints found in this and other forums on the web,
thanks to all the people who worked on this solution!!!
Download the "change_passwd". Follow the instruction from the plugin.
Change some files as follow:
1)Set these values in config.php:
$overridePathToChpasswd = '/usr/bin/pwpolicy';
$pathToPw = '/usr/bin/pwpolicy';
2)In options.php I commented out the lines below if (! empty($pathToPw))
//$fd = popen("$pathToPw usermod $safe_user -h 0 2>&1", 'w+');
//fwrite($fd, $safe_newpw);
//$ret = fread($fd, 4096);
//pclose($fd);
add:
$cmd = "$overridePathToChpasswd -a $safe_user -p $safe_oldpw -u $safe_user -setpassword $safe_newpw";
exec($cmd, $capt, $ret);
3)In functions.php change this line:
Line 28 of this file is trying call a function that has changed names.
CHANGE:
compatibilitycheck_plugin_setup('changepasswd', array('config.php'));
TO:
checkplugin_setup('changepasswd', array('config.php'));
4) In options.php:
Line 39 of this file is trying to include a file from src instead of
include where validate.php actually lives.
CHANGE:
include_once ('../src/validate.php');
TO:
include_once ('../include/validate.php');
Enjoy!

I am not going to say that I originated this hack, but since I came up with the hack to the plugin and it works for me, and I also implemented some other functions like checking for alpha and numeric characters (since we have that set on our LDAP password policy), here you go. I would post it on our server here at work, but I figured someone might have a better place for it, maybe petrobyte or someone can host it.

Hope it works for ya'll!
If you plan on making the hack yourself, it helps to have an understanding of php and HTML, and a good understanding of using the "command line".
