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";
}
}

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;
}
$username = $_POST['username'];
$password = $_POST['password'];
$ldaphost = "ldaps://corpldap.xxx.net";
$ldapUsername = "cn=$username,ou=people,dc=xxx,dc=net";
$ldapPassword = "$password";
$ds = ldap_connect($ldaphost,636) or die("\r\nCould not connect to LDAP server\r\n");
echo $ds; //this output 'Resource id #21'
ldap_set_option($ds, LDAP_OPT_REFERRALS, 0);
if (!ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3)) {
print "Could not set LDAPv3\r\n";
} else {
// now we need to bind to the ldap server
echo 'success'; //echo success output
$bth = ldap_bind($ds) or die("\r\nCould not connect to LDAP server\r\n");
}
I get 'Resource id #21 success
Could not connect to LDAP server'
so ldap_bind is failing
stack trace on error log:
PHP Warning: ldap_bind(): Unable to bind to server: Can't contact LDAP server
How can i fix this? Please help.
Please note: i also tried $ldaphost = "ldaps://corpldap.xxx.net:636";
I also tried echoing php_info() which shows ldap enabled.
My aim is to change passwords in Active Directory through a web interface using PHP & IIS.
I have been following the instructions on http://www.ashleyknowles.net/2011/07/iis-php-and-ldaps-with-active-directory/
Prior to following these instructions I could not get a bind to the AD for an LDAPS connection, however after following these instructions it seems to successfully connect, yet gives an error of "Server is unwilling to perform" when I attempt to change the "unicodePwd" value.
Please note that the code below will successfully change any other value of a user in the AD.
<?php
$ldaprdn = 'CN=Admin User,OU=*******,OU=Staff,OU=********,DC=********,DC=*******,DC=******,DC=*****';
$ldappass = "*******"; // associated password
$ldapconn = ldap_connect("ldaps://***.***.***.***:636" ) or die("Could not connect to LDAP server.");
ldap_set_option($ldapconn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldapconn, LDAP_OPT_REFERRALS, 0);
if ($ldapconn) {
// binding to ldap server
$ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);
// verify binding
if ($ldapbind) {
echo "LDAP bind successful...";
$username = '******';
$dn = "CN=Bob Smith,OU=******,OU=******,OU=******,DC=******,DC=******,DC=******,DC=******";
$newPassword = 'blah';
$newEntry = array('unicodePwd' => encodePwd($newPassword));
print_r($newEntry);
if(ldap_mod_replace($ldapconn, $dn, $newEntry)) {
print "<p>succeded</p>";
} else {
print "<p>failed</p>";
}
print_r(ldap_error($ldapconn));
} else {
echo "LDAP bind failed...";
print_r(ldap_error($ldapconn));
}
}
// Credit: http://www.cs.bham.ac.uk/~smp/resources/ad-passwds/
function encodePwd($pw) {
$newpw = '';
$pw = "\"" . $pw . "\"";
$len = strlen($pw);
for ($i = 0; $i < $len; $i++)
$newpw .= "{$pw{$i}}\000";
$newpw = base64_encode($newpw);
return $newpw;
}
?>
SOLVED!!
It turns out that by following the Ashley Knowles tutorial, I was successfully establishing a SSL connection over LDAP, however the error was occurring because of the password encoding.
The credit for the successful password encoding goes to hd42 on this forum post, which enabled me to modify my code accordingly.
Therefore, once you have correctly installed the certificates etc in the harddrive on the IIS server, this code will successfully modify a user password in Active Directory using PHP through an IIS web server (assuming that the $ldaprdn user has sufficient admin rights):
<?php
$ldaprdn = 'CN=Admin User,OU=*******,OU=Staff,OU=********,DC=********,DC=*******,DC=******,DC=*****';
$ldappass = "*******"; // associated password
$ldapconn = ldap_connect("ldaps://***.***.***.***:636" ) or die("Could not connect to LDAP server.");
ldap_set_option($ldapconn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldapconn, LDAP_OPT_REFERRALS, 0);
if ($ldapconn) {
// binding to ldap server
$ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);
// verify binding
if ($ldapbind) {
echo "LDAP bind successful...";
$dn = "CN=Bob Smith,OU=******,OU=******,OU=******,DC=******,DC=******,DC=******,DC=******";
$newPassword = 'blah';
$newPassword = "\"" . $newPassword . "\"";
$newPass = mb_convert_encoding($newPassword, "UTF-16LE");
$newEntry = array('unicodePwd' => $newPass);
print_r($newEntry);
if(ldap_mod_replace($ldapconn, $dn, $newEntry)) {
print "<p>succeded</p>";
} else {
print "<p>failed</p>";
}
print_r(ldap_error($ldapconn));
} else {
echo "LDAP bind failed...";
print_r(ldap_error($ldapconn));
}
}
I am trying to implement LDAP authentication into our company web portal. I can successfully connect to the host, but I cannot seem to get a successful bind with my Active Directory credentials. Looking for some help on what could possibly be going wrong. Any help, tips, or advice would be greatly appreciated.
$username = $_POST['username'];
$password = $_POST['password'];
$host = "xxx.xxx.xxx.xxx";
$port = "389";
$connection = ldap_connect($host, $port) or die("Could not connect to LDAP server.");
ldap_set_option($connection, LDAP_OPT_PROTOCOL_VERSION, 3);
if ($connection) {
$bind = ldap_bind($connection, $username, $password);
if ($bind) {
echo "LDAP bind successful";
}
else {
echo "LDAP bind failed";
}
}
I had the same problem recently enough and the solution was to add the domain to the username.
$isAuth = ldap_bind($ldap_conn,$_POST['username'].$ldap_settings['adDomain'], $_POST['password']);
Where $ldap_settings['adDomain'] was "#your_domain"
