PHP LDAP Get User Attributes, Including Associated Groups

Question

What is the best way to run a search on the current user to retrieve all attributes, including associated groups in Active Directory using LDAP / PHP?

For attributes, mainly just first name, last name, and display name.

For associated groups, just the groups the user is a member of, such as the memberOf function.

I've tried a few options, but can't seem to get the right filter / search combination and most examples cover retrieving lists of users where there's a known group.

I've tried running this after a successful bind:

$attributes = array("displayname");
$filter = "(&(sAMAccountName=$username))";
$result = ldap_search($ds, $ldapconfig['basedn'], $filter, $attributes);
$entries = ldap_get_entries($ds, $result);
if($entries["count"] > 0){
  echo "displayName: ".$entries[0]['displayname'][0]."<br/>";
 } else {
 echo("msg:'".ldap_error($ds)."'</br>");
 }

Which returns the following error: "No such object".

UPDATE:

This is the latest block I've tried and am able to get results when I print_r the $info variable, however the for clause is still erring out somewhere. I changed the basedn to just the dc attributes:

$filter="($SearchField=$SearchFor)";
$sr=ldap_search($ds, $basedn, $filter, $LDAPFieldsToFind);
$info = ldap_get_entries($ds, $sr);

if($info["count"] > 0) {
    for ($x=0; $x<$info["count"]; $x++) {
        $sam=$info[$x]['samaccountname'][0];
        $giv=$info[$x]['givenname'][0];
        $tel=$info[$x]['telephonenumber'][0];
        $email=$info[$x]['mail'][0];
        $nam=$info[$x]['cn'][0];
        $dir=$info[$x]['homedirectory'][0];
        $dir=strtolower($dir);
        $pos=strpos($dir,"home");
        $pos=$pos+5;
            if (stristr($sam, $SearchFor) && (strlen($dir) > 8)) {
              print "\nActive Directory says that:\n";
              print "CN is: ".$nam." \n";
              print "SAMAccountName is: ".$sam." \n";
              print "Given Name is: ".$giv." \n";
              print "Telephone is: ".$tel." \n";
              print "Home Directory is: ".$dir." \n";
            }   
    }
    }

The print_r of the results are:

( [count] => 1 [0] => Array ( [cn] => Array ( [count] => 1 [0] => George ) [0] => cn [givenname] => Array ( [count] => 1 [0] => George ) [1] => givenname [memberof] => Array ( [count] => 4 [0] => CN=EQCStaff,CN=Users,DC=EQC,DC=local [1] => CN=RDS Users,OU=Security Groups,OU=Service,DC=EQC,DC=local [2] => CN=SFTP Client Folders,OU=Security Groups,OU=Service,DC=EQC,DC=local [3] => CN=EQC Staff,OU=Security Groups,OU=Service,DC=EQC,DC=local ) [2] => memberof [samaccountname] => Array ( [count] => 1 [0] => gortiz ) [3] => samaccountname [mail] => Array ( [count] => 1 [0] => [email protected] ) [4] => mail [count] => 5 [dn] => CN=George,OU=Users,OU=Accounts,DC=EQC,DC=local ) )

Here's a script we have for dumping AD information, maybe it will help you:

<?php
$ldap_columns = NULL;
$ldap_connection = NULL;
$ldap_password = 'top_secret_password';
$ldap_username = 'top_secret_username@'.LDAP_DOMAIN;

//------------------------------------------------------------------------------
// Connect to the LDAP server.
//------------------------------------------------------------------------------
$ldap_connection = ldap_connect(LDAP_HOSTNAME);
if (FALSE === $ldap_connection){
    die("<p>Failed to connect to the LDAP server: ". LDAP_HOSTNAME ."</p>");
}

ldap_set_option($ldap_connection, LDAP_OPT_PROTOCOL_VERSION, 3) or die('Unable to set LDAP protocol version');
ldap_set_option($ldap_connection, LDAP_OPT_REFERRALS, 0); // We need this for doing an LDAP search.

if (TRUE !== ldap_bind($ldap_connection, $ldap_username, $ldap_password)){
    die('<p>Failed to bind to LDAP server.</p>');
}

//------------------------------------------------------------------------------
// Get a list of all Active Directory users.

User inventor96 has suggested using 11644473600 instead of 11676009600. I can confirm 11644473600 is correct in a Linux environment - my guess is that inventor96 is in a Windows environment.
