PHP LDAP Get User Attributes, Including Associated Groups - php

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] => user#domain.com ) [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.
//------------------------------------------------------------------------------
$ldap_base_dn = 'DC=xyz,DC=local';
$search_filter = "(&(objectCategory=person))";
$result = ldap_search($ldap_connection, $ldap_base_dn, $search_filter);
if (FALSE !== $result){
$entries = ldap_get_entries($ldap_connection, $result);
if ($entries['count'] > 0){
$odd = 0;
foreach ($entries[0] AS $key => $value){
if (0 === $odd%2){
$ldap_columns[] = $key;
}
$odd++;
}
echo '<table class="data">';
echo '<tr>';
$header_count = 0;
foreach ($ldap_columns AS $col_name){
if (0 === $header_count++){
echo '<th class="ul">';
}else if (count($ldap_columns) === $header_count){
echo '<th class="ur">';
}else{
echo '<th class="u">';
}
echo $col_name .'</th>';
}
echo '</tr>';
for ($i = 0; $i < $entries['count']; $i++){
echo '<tr>';
$td_count = 0;
foreach ($ldap_columns AS $col_name){
if (0 === $td_count++){
echo '<td class="l">';
}else{
echo '<td>';
}
if (isset($entries[$i][$col_name])){
$output = NULL;
if ('lastlogon' === $col_name || 'lastlogontimestamp' === $col_name){
$output = date('D M d, Y # H:i:s', ($entries[$i][$col_name][0] / 10000000) - 11676009600); // See note below
}else{
$output = $entries[$i][$col_name][0];
}
echo $output .'</td>';
}
}

}
echo '</table>';
}
}
ldap_unbind($ldap_connection); // Clean up after ourselves.

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.
