using LDAP to link to Active Directory?

[davil]

Hi everyone I'm doing a helpdesk project where I work but still stumped by this LDAP . now I'm a bit of a n00b in this area so bear with me.

I'm using Uniform Server from www.uniformserver.com and I've got the LDAP PHP extension working. I'm trying to find out how to do a basic Active Directory query with PHP, I'll eventually integrate this into my program and it will have Active Directory user authentication as well as a 2d mapping system that uses SVG etc. etc. - I can't wait to see it finished and working, but the LDAP portion of this project has stumped me a bit. The trouble I'm having is as follows:

I have the way my Domain is setup below:

For obvious reasons, I've renamed the domain and removed some of the containers or whatever they're called. Anyway, here's my code

<?php

$dn = "OU=Users,DN=blah,DN=yah,DN=yakety,DN=ie";

$attributes = array("displayname", "l");

$filter = "(cn=*)";

$ad = ldap_connect("ldap://mydomaincontroller")
         or die("Couldn't connect to AD!");

ldap_set_option($ad, LDAP_OPT_PROTOCOL_VERSION, 3);

$bd = ldap_bind($ad,"[e-mail]","mypassword")
      or die("Couldn't bind to AD!");

$result = ldap_search($ad, $dn, $filter, $attributes);

$entries = ldap_get_entries($ad, $result);

for ($i=0; $i<$entries["count"]; $i++)
{
    echo $entries[$i]["displayname"]
         [0]."(".$entries[$i]["l"][0].")<br />";
}
ldap_unbind($ad);
?>

and all I get is:
Warning: ldap_search() [function.ldap-search]: Search: Operations error in W:\www\ad3.php on line 17

Warning: ldap_get_entries(): supplied argument is not a valid ldap result resource in W:\www\ad3.php on line 19

Can anybody please help me? I just need a basic example to show me how to interface with my AD - I'm nearly there I can almost taste it!

I've also tried
$dn = "OU=Users,DN=blah,DN=yah,DN=yakety,DN=ie";
$dn = "cn=Users,DN=blah,DN=yah,DN=yakety,DN=ie";
$dn = "DN=blah,DN=yah,DN=yakety,DN=ie";
$dn = "OU=Users,DC=blah,DC=yah,DC=yakety,DC=ie";

and none of these seem to work!!! What am I doing wrong? I'm sure that it's connecting to the server because when I tried with the wrong password it said
incorrect credentials or something. PLEASE HELP!!!!!

I'm also experiencing the same errors and would love to see the response or fix for this.

Thanks in advance.

I'm also working on a script to connect and authenticate users against Active Directory - and I was getting the same error:

Warning: ldap_search() [function.ldap-search]: Search: Operations error in...

Try this - right after this line:

ldap_set_option($ad, LDAP_OPT_PROTOCOL_VERSION, 3);

add the following:

if (!ldap_set_option($ldap, LDAP_OPT_REFERRALS, 0)) {
	exit('Failed to set opt referrals to 0');
}

I tried that and it got rid of that ldap_search() warning.
