I made login via LDAP, but I would like only 3 people to access the site.
They are members of different groups, and I do not want to give permission to the whole group.
How to make a $username comparison with specific AD usernames? I try this but not working...
$username = strip_tags($_POST['username']);
$password = stripslashes($_POST['password']);
$account_suffix = 'domain';
$hostname = 'ldap://hostname';
$con = ldap_connect($hostname);
if (!is_resource($con)) trigger_error("Unable to connect to $hostname",E_USER_WARNING);
ldap_set_option($con, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($con, LDAP_OPT_REFERRALS, 0);
if (!$username = 'specific_usersname') die("HTTP Error 401.1 - Unauthorized: Access is denied");
if (ldap_bind($con,$username . $account_suffix, $password)) echo 'Access granted!';
else echo 'Access Denied!';

I have a functioning code that creats an Ldap connection to an online test server.
<?php
$ldap_dn = "uid=".$_POST["username"].",dc=example,dc=com";
$ldap_password = $_POST["password"];
$ldap_con = ldap_connect("ldap.forumsys.com");
ldap_set_option($ldap_con, LDAP_OPT_PROTOCOL_VERSION, 3);
if(#ldap_bind($ldap_con,$ldap_dn,$ldap_password))
{
$_SESSION['username'] = $_POST["username"];
header("Location: Startseite.php");
}
else
{
echo "Invalid Credential";
}
?>
Now i want to change the code to connect to a local Windows server and retrieve data from the active directory.
This connection should be an Ldaps.
Here is the code i tried.
<?php
$ldap_dn = "uid=".$_POST["username"].",dc=ULTIMATE,dc=local";
$ldap_password = $_POST["password"];
$ldap_con = ldap_connect("ldaps://192.168.***.**:636,OU=ULTIMATE,DC=ultimate,DC=local");
ldap_set_option($ldap_con, LDAP_OPT_PROTOCOL_VERSION, 3);
if(#ldap_bind($ldap_con,$ldap_dn,$ldap_password))
{
$_SESSION['username'] = $_POST["username"];
header("Location: Startseite.php");
}
else
{
echo "Invalid Credential";
}
?>
And i get the following error
Warning: ldap_connect(): Could not create session handle: Bad parameter to an ldap routine in C:\xampp\htdocs\Kulinarik\ldap.php on line 10
Why is it a bad parameter ?
EDIT
So the Active directory is Passwort protected and the users who want to start the query have no rights.
So i would have to make a Bind with the Credentials of the Sysadmin and then make a query inside the active directory with the Credentials of the users.
Is that right?
Try something like:
$ldap_con = ldap_connect("ldaps://192.168.***.**:636");
Without ,OU=ULTIMATE,DC=ultimate,DC=local part.
So, I have an LDAP directory with Okta set up. I am having trouble connecting to it using PHP. Here's my code:
$domain = 'phishingboxdecember15thaccount.ldap.okta.com';
$username = 'USERNAME';
$password = 'PASSWORD';
$ldapconfig['host'] = '44.234.52.17'; // I got this by pinging the domain. I guess that's correct?
$ldapconfig['port'] = 636;
$ldapconfig['basedn'] = 'dc=phishingboxdecember15thaccount,dc=okta,dc=com';
$ds=ldap_connect($ldapconfig['host'], $ldapconfig['port']);
ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ds, LDAP_OPT_REFERRALS, 0);
$dn="ou=users,".$ldapconfig['basedn'];
$bind=ldap_bind($ds, $username .'#' .$domain, $password);
print_r($bind);
$isITuser = ldap_search($bind,$dn,'(&(objectClass=User)(sAMAccountName=' . $username. '))');
if ($isITuser) {
echo("Login correct");
} else {
echo("Login incorrect");
}
Yet this never works. Always get "Login incorrect", and I am certain that I'm using the correct password (although, I'm not sure about the username part - I just use the username I enter to login to my Okta admin account, I'm assuming that's correct?).
Do you have any ideas/tips on how I can connect to the Okta LDAP using PHP?
The settings you need are in the documentation here. The one that jumps out to me is the host should be of the form <org_subdomain>.ldap.okta.com as you have in the domain variable.
I think your search will need to be tweaked to:ldap_search($bind,$dn,'(&(objectClass=inetOrgPerson)(uid=' . $username. '))'); but that won't be stopping your login.
I want to use my system login password to php login page. So that i used the LDAP concept in my project. I have mentioned below my coding, that is everything fine. But When i run this code, the result shows "Invalid user". I don't know why this was showing wrongly.
$ldaphost = 'abc.co.in';
$ldapport = '389';
$username = '4444';
$password = '4444pass';
$ldap = ldap_connect($ldaphost, $ldapport)
or die("Could not connect to $ldaphost");
ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION, 3);
$user = "uid=$username,dc=abc,dc=co,dc=in";
$bind = #ldap_bind($ldap, $user, $password);
if ($bind) {
echo "<br />Valid user";
} else {
$msg = "<br />Invalid user";
echo $msg;
}
Below the result:
What is fault in my code or i need to anything add?
Please find and solve this request. That will more helpful to me.
Thank you advance...
This is how my ldap thing works. change your ldap host to be either "ldap://abd.asd.co:389' or "ldaps://asd.basd.co:636".
function verify_user() {
$user = $_REQUEST['user'];
$passwd = $_REQUEST['pass'];
// Bind to LDAP to check is user is valid
$server = "ldaps://ldap.server.com:636";
$dn = "uid=$user, ou=People, ou=something, dc=other, dc=whatever";
// Create a fake password if needed to keep people from anonymously
// binding to LDAP
if($passwd == '') { $passwd = "p"; }
$ldap = ldap_connect($server) or die("Can't connect to LDAP server!");
ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_start_tls($ldap);
if($ldap) {
$bnd = #ldap_bind($ldap, $dn, stripslashes($passwd));
if(!$bnd) {
sleep(5);
echo "<br>Error: Bad Username or Password!<br>";
exit;
}
}
header("Location: {$_REQUEST['url']}"); /* Redirect browser */
exit;
}
My company recently changed domains due to an ownership change and I am having an issue getting my LDAP bind to complete on the new domain.
My connect command creates the resource correctly but when I go to bind I get the error.
"Warning: ldap_bind(): Unable to bind to server: Strong(er) authentication required"
I am not using ldaps. I have confirmed I have the correct domain url for LDAP.
$ad is the resource, $dmun is the username with domain added and the $pw is the password.
$bd = ldap_bind($ad,$dmun,$pw);
It's an intranet site.
Try This code. This code worked for me
$username = 'username';
$password = 'password';
$ldap_host = "domain.com";
$ldap_port = 389;
$base_dn = "DC=domain,DC=com";
$filter = '(sAMAccountName=' . $username . ')';
$connect = ldap_connect($ldap_host, $ldap_port) or exit("Error : Could not connect to LDAP server.");
if ($connect) {
ldap_set_option($connect, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($connect, LDAP_OPT_REFERRALS, 0);
if (#$bind = ldap_bind($connect, "$username#domain.com", $password)) {
echo "Bind Successfull";
} else {
echo "Invalid Username / Password";
}
}
This is my LDAP code to authenticate a user. I have to show users full name once the user had logged in. How do I get the full name of the user from AD?
<?php
FUNCTION ldapCheckLogin ($username, $upasswd) {
$ldaphost = '10.20.30.40';
$ldapport = 389;
$ds = ldap_connect($ldaphost, $ldapport)
or die("Could not connect to our login server!");
ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ds, LDAP_OPT_REFERRALS, 0);
ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, 7);
if ($ds)
{
//$username = 'na\'; //OK - Congratulations! na\spups is authenticated.
$upname = 'iap\\' . $username;
$ldapbind = #ldap_bind($ds, $upname, $upasswd);
if ($ldapbind) {
//print "Congratulations! $username is authenticated.<BR><BR>";
ldap_unbind( $ds );
return true;
} else { //print "$username - Access Denied!<BR><BR>";
return false;
}
} else {
return false;
}
}
?>
You need to retrieve the user's entry using ldap_search with the user's samAccountName e.g. (samaccountname=$username) or userPrincipalName e.g. (userprincipalname=$username . "#" . $domain.com ) as the filter attribute.
samaccountname is only unique in the domain whereas userPrincipalName is unique across the entire forest.
When you perform the ldap_search you need to include the cn or displayName in the attributes to return.
If the search is successful then you need to process the resulting entry and extract the cn and/or the displayName.
