I have serious trouble figuring out which credentials to use to connect to the ad in php.
I can connect successfully using ldp.exe with generic function type and the right domain, user, and password. With any other option set in ldp.exe I can only connect anonymous.
In php I have no chance. I'm not very familiar with ldap, so I am kinda lost here.
Here some php code:
$ldap_host = "ldap://<dc>:389";
$ldap_user = "<username>";
$ldap_pw = "<pw>";
$ldap_domain = "<full domain>";
$connection = ldap_connect($ldap_host) or die("Could not connect to LDAP server.");
//$user = $ldap_user;
$user = $ldap_user."#".$ldap_domain;
//$user = $ldap_user;
//$user = "uid=".$ldap_user;
//$user = $ldap_domain."\\".$ldap_user;
//$user = "User=$ldap_user";
//$user = "cn=".$ldap_user;
//$user = "CN=".$ldap_user.",OU=<someOU>,OU=<someOU>,DC=<DC1>,DC=<DC2>";
ldap_bind($connection, $user, $ldap_pw);
You can see there some combinations I tried. In ldp.exe it is just the $ldap_user in the username field and $ldap_domain in the domain field. Imho atleast the user#domain and domain\user version should work. It is a kerberos domain, if thats important.
Well I don't think there are code errors. But how do I translate the generic function type of ldp.exe into php?
Here the error message to make it easier to find:
Warning: ldap_bind(): Unable to bind to server: Invalid credentials in ...
I would really appreciate some help.
EDIT: In ldp.exe I seem to use the SSPI method. I thought generic picks the method it self so far. Does it have something to do with ldap_sasl_bind() ? The server specifies on connection he is capable of the following:
supportedSASLMechanisms: GSSAPI; GSS-SPNEGO; EXTERNAL; DIGEST-MD5;
While only GSSAPI (SSPI ????) seems to work.
EDIT2: Here some other output of ldp.exe after an successful authentication:
res = ldap_bind_s(ld, NULL, &NtAuthIdentity, 1158); // v.3
{NtAuthIdentity: User='<username>'; Pwd= <unavailable>; domain = '<full domain'.}
Authenticated as dn:'<username>'.
Try specifying the port as well into a variable
$ldapPort = 389;
I would ignore the host part and just try connecting to your server (you have it as domain) Check to see if your ldap bind is working
// Handle login requests
$ds = ldap_connect($ldapServer, $ldapPort);
if (ldap_bind($ds, $user, $password)) {
// Successful auth
$_SESSION['lastactivity'] = time();
$_SESSION['username'] = $user;
$_SESSION['password'] = $password;
return $ds;
} else {
// Auth failed
header("Location: failpage.php?fail=1"); //bad credentials
exit;
}

I want to pass username directly to the ldap without user interaction.
I am able to get clients hostname,ip address,but i am unble to get user profilename(username) from intranet in php, help me to get username
function checkingLogin($username, $pass, $domain) {
$dom = "$domain\\"; //Domain Prefix for UNAME which ouputs "domain\"
$user = $dom . $u;
$hostname = 'ldap://abc.com';
$baseDN = 'OU=users, DC=abc, DC=com'; //Narrow down if you have alot of objects as search could take along time
$search = "(samaccountname=$u)"; //Compare with Username
$ldap = ldap_connect($hostname);
if ($ldap) {
$ldapbind = ldap_bind($ldap, $user, $pass);
if ($ldapbind) {
$ldapSearch = ldap_search($ldap, $baseDN, $search);
$entry = ldap_first_entry($ldap, $ldapSearch);
$info = ldap_get_values($ldap, $entry, "displayname");
return $info[0];
}
return false; //Failed Auth
}
return false; //Connection Failed
}
The users browser doesn't provide that information due to security considerations. Otherwise that would mean that the username you use to log into your machine would be sent to every single website. Do you really want that?
Besides that, it would need a very tight integration between the computer and the browser. That could be possible with f.e. Windows and Edge or IE but I'd doubt that that works on Firefox or Chrome.
There are ways though to actually do what you want to do. But they require access to the client-machines and a well-known environment. Then you might be able to setup something like Kerberos to allow logging into your computer and use that token to also authenticate against webservices. But that is not a default setup!
I have put together a basic web-app, the actual web-app itself works fine. However I wanted to add user authentication using our existing ldap server. The ldap script seems to work intermittently though, when logging in the first few attempts will fail with the 'access denied' message then it will authenticate. I ran the script stand alone without the app and the same behavior applies.
I cant seem to tie the problem down anywhere, I can only assume it is occuring on the ldap side and not the php side. I have included the script below, any help would be great.
While writing this, it failed to auth 3 times and passed twice...
<?php
$user = $_POST['login-name'];
$password = $_POST['login-pass'];
$ldap_user = 'uid='.$user.',ou=people,dc=ourdomain,dc=com,dc=au';
$ldap_pwd = $password;
$ldaphost = 'ldap://ldapserver.domain.com';
$ldapport = 389;
$ds = ldap_connect($ldaphost, $ldapport)
or die("Could not connect to $ldaphost");
if ($ds)
{
$username = $ldap_user;
$upasswd = $password;
$ldapbind = ldap_bind($ds, $username, $upasswd);
if ($ldapbind)
{
//print "Congratulations! $username is authenticated.";
header('Location: message.html');
}
else
{print "Access Denied!";}
}
?>
You probably should set the LDAP-protocol version to 3 using
ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
before calling ldap_bind().
I've found this at http://php.net/manual/de/function.ldap-bind.php#72795
I am trying to establish connection using sftp class
my code:
$host = 'some ip address';
$username = 'username';
$pass = 'password';
$sftp = new SFTPConnection($host, 22);
$sftp->login($username, $pass);
When i run this script i get message Could not authenticate with username and password
When i use same user and pass in fileZilla with sftp, then is ok, I can establish connection, but with script i cant
Anyone know what is the problem?
Ok, here what was the problem...
My IP address wasnt been allowed on FTP server?! Now when they put my IP on whitelist, everything working just fine.
Thank you guys for your effort.
Try to add this code in your sftp.php in login(){} function. Then tell what error does it give:
if (!extension_loaded('ssh2'))
{
throw new Exception("Extension ssh2 has to be loaded to use this class. Please enable in php.ini.");
}
if (! #ssh2_auth_password($this->connection, $username, $password))
throw new Exception("Could not authenticate with username $username " . "and password $password.");
$this->sftp = #ssh2_sftp($this->connection);
if (! $this->sftp)
throw new Exception("Could not initialize SFTP subsystem.");
Edit your code to do the following[ as some people say that we should authenticate both via username_password and as well as hostKeyAuthentication ]
-------------------------------
The above description shows that:
The issue lies in the php extension assuming that you’re going to authenticate either with a password or with a public key. Because of that assumption, authenticating with a password will give you a failure and could throw you off into the wrong direction (brief description is in the link: Must Read).
$connection = ssh2_connect($host, $port);
ssh2_auth_password($connection, $username, $password);
if (ssh2_auth_pubkey_file($connection, $username, $pubkey, $privatekey)) {
echo "Public Key Authentication Successful";
}
else {
echo 'Public Key Authentication Failed' ;
return false;
}
I have some code that uses PHP and LDAP to connect to AD:
$host = 'ldap://stack.overflow.com';
$port = 389;
$username = 'stackOverflow';
$password = 'IaMP4ssWord';
$dn = 'CN=Users, DC=STACK, DC=OVERFLOW, DC=COM';
$cond = '(&(objectcategory=user)(displayname=*))';//All users that have a displayname
if($ldap = ldap_connect($host, $port))
{
if(ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION, 3))
{
if(ldap_bind($ldap, $username, $password))
{
$attrs = array('displayname', 'mail');
if($rs = ldap_search($ldap, $dn, $cond, $attrs))
{
$results = ldap_get_entries($ldap, $rs);
echo "<pre>";print_r($result);echo "</pre>";//Print the results
}
}
else
{ echo 'Binding failed';}
}
else
{ echo 'Setting options failed';}
}
else
{ echo 'Connection failed'; }
Now this code works just fine. It print out every user that has a displayname in AD.
Problem is for the username/password binding i am using my own user credential to bind to the server.
I would like to know if there is a way to bind using the servers credentials.
I am setup using PHP 5.3 + IIS on windows server 2008 R2 for both the server with IIS and the one that has AD.(two different VM).
I also know that IIS has a AD account named IISStackOverflow but I don't know the password or even if it has a password...
Thanks!
Oh! I tried changing $username to IISStackOverflow and $password to ''
But it gave invalid credential error.
--EDIT--
Do I have to do the binding part at all? (If I am only reading data)
As you run it from server itself, and you just want to read I would try to use :
...
if(ldap_bind($ldap))
...
According to PHP documentation if bind_rdn and bind_password are not specified, an anonymous bind is attempted.
Then if your anonymous logon is refused (this should not be, because running under IIS on the server your code is at least executed as a domain user) you will find there how to enable anonymous LDAP binds to Windows Server. This used to work forme on W2K8, Inever test it on W2K12.
I've been looking at a couple of guides (and the PHP manual) trying to validate AD users on an intranet site I'm about to make. This is the first time I've used ldap_connect, and I haven't had the best of luck.
Could anyone look at my code and see what I'm missing?
Thanks.
<?php
$user = "08jf1";
$password = "pass";
// Active Directory server
$ldap_host = "10.43.48.5";
// Active Directory DN
$ldap_dn = "OU=CSE-W7,OU=Students-W7,DC=server,DC=local";
// Domain, for purposes of constructing $user
$ldap_usr_domain = "#server.local";
// Connect to AD host
$ldapconn = ldap_connect("10.43.48.5");
if ($ldapconn) {
$bind = ldap_bind($ldap_host, $ldap_dn, $user . $ldap_usr_domain, $password);
if ($bind) {
echo "Verified user";
//$_SESSION['username'] = $session_username;
//$_SESSION['password'] = $session_password;
} else {
echo "User does not exist";
}
}
?>
Edit: I can confirm ldap is enabled though phpinfo!
Is that syntax of ldap_bind correct?. Isn't it ldap_bind($ldapconn,$rdn,$password) ?
Binding may need a elevated privilege or authbind wrapper. Refer to authbind for ldap. LDAP AuthBind
