If you want to disable an account in an Active Directory of Windows, 
you may try this (it works for me in a Win2k environment):

(foo.bar should be replaced in "$ldapBase" to the correct
 domain, e.g. "DC=phpfreackx,DC=com" if your domain is phpfreackx.com)

domctrl = domain controller
domadlogin = domain admin login
domadpw = domain admin password
username = loginname of useraccount (e.g. "john.doe")
enable =1 (if you want to enable it, 0 if it should be disabled)

<?php
function userchange($username,$enable=1,$domadlogin,$domadpw,$domctrl)
{
$ldapServer = $domctrl;
$ldapBase = 'DC=foo,DC=bar';
$ds = ldap_connect($ldapServer);
if (!$ds) {die('Cannot Connect to LDAP server');}
$ldapBind = ldap_bind($ds,$domadlogin,$domadpw);
if (!$ldapBind) {die('Cannot Bind to LDAP server');}
ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
$sr = ldap_search($ds, $ldapBase, "(samaccountname=$username)");
$ent= ldap_get_entries($ds,$sr);
$dn=$ent[0]["dn"];
// Deactivate
$ac = $ent[0]["useraccountcontrol"][0];
$disable=($ac |  2); // set all bits plus bit 1 (=dec2)
$enable =($ac & ~2); // set all bits minus bit 1 (=dec2)
$userdata=array();
if ($enable==1) $new=$enable; else $new=$disable; //enable or disable?
$userdata["useraccountcontrol"][0]=$new;
ldap_modify($ds, $dn, $userdata); //change state
$sr = ldap_search($ds, $ldapBase, "(samaccountname=$username)");
$ent= ldap_get_entries($ds,$sr);
$ac = $ent[0]["useraccountcontrol"][0];
if (($ac & 2)==2) $status=0; else $status=1;
ldap_close($ds);
return $status; //return current status (1=enabled, 0=disabled)
}   

// use this to disable an account:
// userchange('[email protected]',0,'[email protected]', 'secret','domctrl.foo.bar'); 
// ..but this to enable it:
// userchange('[email protected]',1,'[email protected]', 'secret','domctrl.foo.bar'); 
?>
