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"

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";
}
}
I am trying to connect to LDAP server but I am always getting 'Error trying to bind: invalid credentials' when I supplied the right credentials. How do I troubleshoot this issue? How do I know if connection is successful? I am stuck here please let me know if there are any suggestions.
<?php
$domain = 'school123.edu';
$username = 'test';
$password = 'password';
$ldapconfig['host'] = 'server123';
$ldapconfig['port'] = 389;
$ldapconn=ldap_connect($ldapconfig['host'], $ldapconfig['port']);
ldap_set_option($ldapconn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldapconn, LDAP_OPT_REFERRALS, 0);
// binding to ldap server
$ldapbind = ldap_bind($ldapconn, $username, $password) or die ("Error trying to bind: ".ldap_error($ldapconn));
// verify binding
if ($ldapbind) {
echo "LDAP bind successful...<br /><br />";
} else {
echo "LDAP bind failed...";
}
$dn='dc=school123,dc=edu';
$result = ldap_search($ldapbind,$dn,'(&(objectClass=*)(sAMAccountName=' . $username. '))');
$entries = ldap_get_entries($ldapconn, $result);
echo $entries["count"]." entries returned\n";
// all done? clean up
ldap_close($ldapconn);

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 having a little trouble with my PHP LDAP login. My first bind is successful, but my second bind is not even if the credentials are correct. I tried using the credentials I use to the second bind in the first one to make sure it worked, and sure enough it can bind it at the first one. Why am I not being able to bind the second time?
<?php
// Define $myusername and $mypassword
$username=$_POST['username'];
$password=$_POST['password'];
// using ldap bind
$ldaprdn = 'uid=MYUID,ou=special,ou=people,o=myo.com,dc=mydc,dc=com'; // ldap rdn or dn
$ldappass = 'PASSWORD'; // associated password
// connect to ldap server
$ldapconn = ldap_connect("ldaps://MYLDAPSERVER", ###)
or die("Could not connect to LDAP server.");
if ($ldapconn)
{
// binding to ldap server
$ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);
// verify binding
if ($ldapbind)
{
$result = ldap_search($ldapconn, "ou=people,o=myo.com,dc=mydc,dc=com", "uid=$username");
$info = ldap_get_entries($ldapconn, $result);
$userdn = $info[0]["dn"];
$count = $info["count"];
ldap_unbind($ldapconn);
if ($count == 1)
{
$ldapbinduser = ldap_bind($ldapconn, $userdn, $password);
if ($ldapbinduser)
{
echo "Sucess you made it all the way<br />";
}
else
{
echo "Invalid Login Details, please try again(1001)";
}
}
else
{
echo "Invalid Login Details, please try again(1002)";
}
}
else
{
echo "LDAP bind failed(1000)";
}
}
Although its name might implicate something different, ldap_unbind() actually kills the connection handle so that the connection is not usable any more after an unbind. Remove the ldap_unbind() call from your code and everything should work as expected.
