Failing to query LDAP.

[M4verick]

Hello all! I'm having an issue where I'm trying to query LDAP, however it's failing and returning -

Warning: ldap_get_attributes() expects parameter 2 to be resource, array given in C:\wamp\www\ad.php on line 34.

 

This is running on a WAMP server for use on an internal LAN on a Windows machine.

Here's the code

<?php 
$dn = "DC=ad,DC=fakedomain,DC=com"; 
if (isset($_POST['userid'])){
    $userid = rtrim($_POST['userid']); 
}

if (isset($_POST['criteria'])){
    $cri = rtrim($_POST['criteria']); 
}
    $login = "username@ad.fakedomain.com"; 
    $password = "password"; 

    $ad = ldap_connect("ad.fakedomain.com") 
          or die("Couldn't connect to AD!"); 
    ldap_set_option($ad, LDAP_OPT_PROTOCOL_VERSION, 3); 
    ldap_set_option($ad, LDAP_OPT_REFERRALS, 0); 
          
    $bind = ldap_bind($ad,$login,$password);
    $filter = "($cri=$userid)"; 
    $result = ldap_search($ad,$dn,$filter);
echo $result."<br />";
    $entry = ldap_get_entries($ad,$result);
if (!isset($entry)){
echo "Your query has failed."; }
else {
echo $entry;
$info = ldap_get_attributes($ad,$entry);

for ($i=0; $i<$info["count"]; $i++) {
    $desc = ($info[$i]);
    $detail = ldap_get_values($ad,$entry,$desc);

   echo $info[$i]." </td><td align=left>";
   for ($a=0; $a < $detail["count"]; $a++) {
   echo $detail[$a];
     $b = $a + 1;
} ;};};
    ldap_unbind($ad);
    ?>

 

Can anyone tell me why this is failing? I am a PHP newb, but definitely interested. Thanks!

Warning: ldap_get_attributes() expects parameter 2 to be resource, array given in C:\wamp\www\ad.php on line 34.

 

The second parameter you're giving ldap_get_attributes() is $entry.  Now $entry is obviously an array returned by the method  ldap_get_entries().  You need to change $entry to $result which is a resource returned by ldap_search().

Just to verify we're on the same page, is this what you're saying? Unfortunately I won't be in a position to check until tomorrow, but I am eager. I am slowly discovering the awesomeness that is PHP and you'll prolly be seeing me a bit more in the forums.

 

$filter = "($cri=$userid)";     
$entry = ldap_get_entries($ad,$filter);
$result = ldap_search($ad,$dn,$entry);

No.

 

Change:

 

$info = ldap_get_attributes($ad,$entry);

 

to this:

 

$info = ldap_get_attributes($ad,$result);

 

[M4verick]

That results in -

Warning: ldap_get_attributes(): supplied resource is not a valid ldap result entry resource in C:\wamp\www\ad.php on line 32

 

So, this error is telling me that it is not liking the returned query I'm assuming?

I'm not sure about this, but I have been experimenting with PHP/LDAP the last two weeks and in the beginning I had some weird error messages because the connection and/or bind did not succeed.

 

You might want to try to add 'or die()'-statements to your connection / bind-cmd's.

 

Also: I had to set my ldap-options even before the connection was made (you set it between the connection and the bind)...

I tried your suggestions but it results in the same error.
