Here's an easy way to encode AD "unicodepwd" values from linux... 



Download and install recode... 

http://www.gnu.org/software/recode/recode.html



Then write something like this...

<?php

function ADUnicodePwdValue($plain_txt_value)

{

    return str_replace("\n", "", shell_exec("echo -n '\"" . $plain_txt_value . "\"' | recode latin1..utf-16le/base64"));

}



$user["unicodepwd"] = ADUnicodePwdValue("my_password");



?>

You can use arrays for multiple attributes example:



$entry[mail] = array("newmail@aelana.com","altnewmail@aelana.com");

$results = ldap_mod_add($ldapConnID,$dn, $entry);



or as i did for creating anew user:



$adduserAD["objectClass"] = array("top","person","organizationalPerson","user");

Here is some great information from the OpenLDAP FAQs regarding changing a userPassword attribute with PHP:



http://www.openldap.org/faq/data/cache/347.html



$userpassword = "{SHA}" . base64_encode( pack( "H*", sha1( $pass ) ) );

Before you modify values in your ldap directory, first make sure that you have permission to do so.  In openldap adding the following acl in slap.conf will allow the user to modify their own userpassword.



access to attr=userPassword

        by self write

        by anonymous auth

        by * none

If you do not wish to set up SSL on your active directory, and you are running on Windows, you can use COM and ADSI to set the new password for a user, or to active a user:



<?PHP

// to set a user password

  // server is the ldap server

  // newuser_dn is the full dn of the user you want to modify

  // newuser_password is the password you wish to set for the user



    $ADSI = new COM("LDAP:");

    $user = $ADSI->OpenDSObject("LDAP://".$server."/".$newuser_dn, $adminuser, $adminpassword, 1);

    $user->SetPassword($newuser_password);

    $user->SetInfo();



// to activate a user

    $ADSI = new COM("LDAP:");

    $user = $ADSI->OpenDSObject("LDAP://".$server."/".$newuser_dn, $adminuser, $adminpassword, 1);

    $user->AccountDisabled = false;

    $user->SetInfo();



?>

Using ldap_mod_replace to change a user's password will not set the password using a hashed value, but rather in clear text. There doesn't seem to be a way to use the various password-change protocols (e.g. extended operation) using this API. You might be better off using the ldappasswd command-line tool to perform this function.

Changing a user password in Active Directory.

Securely connect (using ldaps) to the Active Directory and bind using an administrator account.



In this example, $userDn contains the dn of the user I want to modify, and $ad is the Active Directory ldaps connection)



$newPassword = "MyPassword";

$newPassword = "\"" . $newPassword . "\"";

$len = strlen($newPassword);

for ($i = 0; $i < $len; $i++)

        $newPassw .= "{$newPassword{$i}}\000";

$newPassword = $newPassw;

$userdata["unicodepwd"] = $newPassword;

$result = ldap_mod_replace($ad, $userDn, $userdata);

if ($result) echo "User modified!" ;

else echo "There was a problem!";



I found it hard to get a proper encoding for the unicodepwd attribute so this piece of code might help you ;-)

Sometime,we cannot replace ldap_mod_replace  function  with ldap_mod_del function and ldap_mod_add fuction .We  don't have permission to delete an attribute but  we can replace it.

in openldap 2.0.x you can use method with mod_del/mod_add only if the attribute have defined EQUALITY rule.

To modify an attribute with a single value: 


  $entry[mail] = "newmail@aelana.com"; 


  $results = ldap_mod_add($ldapConnID,$dn, $entry); 





To modify an attribute with multiple values: 


  $entry[mail][] = "newmail@aelana.com"; 


  $entry[mail][] = "altnewmail@aelana.com"; 


  $results = ldap_mod_add($ldapConnID,$dn, $entry);





To modify multiple attributes


  $entry[mail][] = "newmail@aelana.com"; 


  $entry[mail][] = "altnewmail@aelana.com"; 


  $entry[c]      = "US";


  $results = ldap_mod_add($ldapConnID,$dn, $entry);

ldap_mod_replace() and ldap_modify() are _exactly_ the same.  So, the comment that ldap_mod_replace() "performs the modification at the attribute level as opposed to the object level", has no root in reality.
