PHP - Remote Ldap

Hi,

I'm completely new to LDAP authentication but have managed to get a fairly smooth working script. However, I was wondering what is the easiest way to get a BASEDN from a Fully Qualified Domain Name.

At the moment I have a loop which would take:

example.com

and turn it into
dc=examplem,dc=com

But is that the best way?

Hi, I haven't worked with PHP in years and was asked to debug something.  Maybe you can help me out since I'm stuck.  This error popped up when we upgraded from PHP 5.3 to 5.4.   It is setting LDAP options.   Here is the code: ldap_set_option($ldapconn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldapconn, LDAP_OPT_REFERRALS, 0) or die ("Could not set option referrals");     Both of these statement are throwing the following error message to the log.   52 is not a valid ldap link resource   Anything I can check or look at? I am a little clueless here.   Thanks    

Hi I am finding that I get a random LDAP search fail the initial time i run a script against 2008R2 when I refresh all is ok ? PHP 5.2.5 get the same thing with the latest version of PHP. any ideas ? its as if the DC is sleeping until you give it a nudge, running on 2008R2 running on vmware.

Hi,
I'm working with the LDAP directory, and using PHP to access it.

I am able to extract the name, departments and phone nos. from the directory.

On the display page, i am looking to make the name column sort A-Z. (Like the "name" will be clickable and will sort the names from A-Z and Z-A )

Would appreciate if someone could suggest approaches to achieve this using PHP

Thanks

I am having trouble authenticating users with LDAP. I can authenticate users when I use "CN" or "givenName" but not when I use "samaccountname", which is the username. CN is just the first + last name.

Does anyone know why only CN and not samaccountname works?


$strUsername = "test"; 
$strPassword = "pass";

$dn = 'samaccountname=' . $strUsername . ',OU=Staff,DC=mydomain,DC=com';

$strDomain = "ldap://localhost/";

$bolAuth = false;

// connect to ldap server
$port = "389";
$objConn = ldap_connect($strDomain);

if ($objConn)
{
if ( $strPassword != null )
{
$bolAuth = ldap_bind($objConn, $dn, $strPassword);
if ( $bolAuth ) {

$search_id = ldap_search($objConn, "OU=Staff,DC=mydomain,DC=com", "(samaccountname=".$strUsername.")");
$entries = ldap_get_entries($objConn, $search_id);
if ($entries["count"] == 1) {
$first_name = $entries[0]["givenname"][0];;
$last_name = $entries[0]["cn"][0]; 

}
}  

}


ldap_close($objConn);
}

if($bolAuth==false){
echo "fail";
return false;
}

Hi Everyone,

Hopefully someone will be able to assist with my problem. Basically, my situation is that we have a server which hosts multiple websites using multiple IP address. One of the new sites we are moving to this server needs an LDAP connection outside of our network. The outside LDAP has already been enabled to accept requests from the specific IP assigned to this site. However, other sites on this server are using other IP addresses.

It seems as if the LDAP authentication request is getting sent by a IP address which is not authorized by the firewall on the outside LDAP server. Thus trouble authenticating.

So, my question is, is there a way to force the ldap_bind request to use a specific IP address to send the request for authentication? Supposedly this can be done using an event handler. However, I don't have much experience with event handlers so am not sure how to go about doing this.

I would appreciate any help or ideas to resolve this situation. Thanks!

Hi,
I am trying to search the employeeid value taken from an mssql db against a LDAP database.
It works but when it cannot found the employeeid on the LDAP db it stops with this error:

Catchable fatal error: Object of class variant could not be converted to string in ldap2.php on line 101

Here is the code.
i've tried with ->value without success .

Please help me.

do {
$sql = "SELECT EMPL.MATR
FROM DOS
ORDER BY DOS.MATR";
 
$result = mssql_query($sql);
while ($myrow = mssql_fetch_array($result))
{

$matr = $myrow['MATR'];
$matr = intval($matr);

//echo $matr;

$strRS = "Select givenname,sn,displayName,mail,SAMAccountName,employeeid,cn from 'LDAP://dom.local/DC=dom,DC=local' where objectClass='user' and employeeid='$matr'";

$RS->Open($strRS, $Conn, 1, 1);
echo $RS['cn'];
echo "<br>";

$RS->Close;

}

$item++; // iterate count through ldapresults

}
while ($item < $Result['count']);
echo '<hr />';
$Conn->Close;

I am new to PHP. I have been trying to do some research online for a few days and not getting very far. I feel like I know less now than I did before I started.

Here's the story:

I've set up a LAMP server that runs a Wiki and AppGini (http://www.bigprof.com/appgini/) - AppGini allows you to "Create web database applications instantly without writing any code" - The only downside we have with it, is it's got it's own set of user accounts. My team all logs in with the default admin account which isn't a big deal but we'd prefer to use LDAP to AD for reasons I won't get into right now.

I emailed AppGini support and asked about LDAP integration. Their response was that it's "a little bit of work" and "You can modify the login authentication function to authenticate using LDAP ... please see the example code he http://code.activestate.com/recipes/101525-ldap-authentication/ (needs some modifications to work with AppGini)"

I've googled around and found 2 dozen different LDAP PHP samples. I've gotten some of them to work. By work I mean they connect to my domain controller and say "success" I'm not actually logged into anything.

So I'm looking for a little help from square one. I need to have a better understanding of how things are supposed to work so I know where I'm supposed to go with all of this. Where do I start? What do I do? What would YOU do?

Hey people!

I'm currently working on an free API that i will be sharing with the web community in the next few months and had a question that much of this project hinges upon:

Is there a way to allow a remote include of one php file from my server?

Case:
I am allowing 2 ways for users to access the APi:

1. Using AJAX or cURL accessing a REST method over POST or GET (This part is already functional)
2. Allowing an include of the API Library
    I'm not sure if it will be completely opensource yet, only free, this is why I don't want to simply provide the source files to users.

Example of what I would like to do:

<?php
include('http://mysite.com/myAPI/classLib.php');
?>


Anybody have a solution for that??


Thanks in advance,

E

On my website, I have a download folder containing several files ranging in size from 6Mb to 700Mb. Users have no problems downloading the smaller files but often have problems downloading the files over 500Mb. We also have an archive of all the files located on a sub-domain on a server in England. Those users that are having problems downloading large files from the main site usually have no problem downloading the large files if we send them the URL for the archive. I've added a button that calls the following script so the users can choose where to download from but have no idea how to code the script.

Here's what I've tried:

// ukdloader script
<?php

$php_scripts = '../../php/';
require $php_scripts . 'PDO_Connection_Select.php';
require $php_scripts . 'GetUserIpAddr.php';
function ukdloader($l_filename=NULL)

{
$ip = GetUserIpAddr();
if (!$pdo = PDOConnect("foxclone_data"))
{    
    exit;
}

    if( isset( $l_filename ) ) {  
        echo <a href="http://foxclone.org/".$l_filename">   /* This is the archive site */
        
        $ext = pathinfo($l_filename, PATHINFO_EXTENSION);
        $stmt = $pdo->prepare("INSERT INTO download (address, filename,ip_address) VALUES (?, ?, inet_aton('$ip'))");
        $stmt->execute([$ip, $ext]) ; 

        $test = $pdo->query("SELECT id FROM lookup WHERE INET_ATON('$ip') BETWEEN start AND end ORDER BY start DESC, end DESC");
        $ref = $test->fetchColumn();
        $ref = intval($ref);

        $stmt = $pdo->prepare("UPDATE download SET ref = '$ref' WHERE address = '$ip'");
        $stmt->execute() ;         
       }
        
    else {
        echo "isset failed";
        }  
}
ukdloader($_GET["f"]);
exit;

Thanks in advance.

folks, i know i may be asking a question that has been answered before but i am asking this here again because i could not find any simple and straightforward answers.

i want to debug my php scripts. no web server is involved. all the scripts are used for parsing and preparing data files...something like we do with unix shell scripting. the scripts reside on a linux box and each script may call functions in other included scripts. i can connect to the linux box using my notebook. on my notebook i have Eclipse and PhpEd. i want to debug those php scripts on the linux box using my notebook's Eclipse or PhpEd. (no webserver or html involved and php cli is already setup and running scripts on the linux box).

If this (using PhpEd and Eclipse on the notebook to remotely debug) is not possible can you please suggest me how do i debug those scripts while i am on the linux server (using command line etc.).

please help me how to set up.

regards,
kali

Hi,

I'm writing some software and I'm wanting to store user statistics on my web-server remotely. My application outputs the statistics into a txt file and asks the user if they would like to submit this data to my server to help the project (statistics gathering  ) and if they submit it I want the information stored in a mysql database on my web-server. I was thinking about passing the data in through the url in an http request to the page, but there's too much data.

I'm interested in finding out if it's possible to upload a file directly to a php script. I could use FTP to place it on my server, but that would require me putting the ftp login into the program, which I don't feel safe about doing that. At least with a php script I'm able to filter and process any input before it's inserted into the database. Is it actually possible to upload directly to my server from a php file in an http request from an application though?

Ok, the database I have been working on the past few days is located on my websites server (1&1) and today I am trying to get a connection to it on a website that is on a different server, but I am getting my echo statement of saying it can't find the database even though I changed it from "localhost" to the physical address of the database.  Any ideas?

Hey guys i'm using the following code to POST data to the HTTPS url given below. But I m unable to perform a remote login and access the rest of the website. Can u find out the flaws in the code snippet and rectify it ? Or suggest a new code snippet.

Also can anyone suggest how to open/read the contents of the login restricted pages on a successful login .



$fullurl = "https://premium.rpnet.biz/login.php/";
$postFields="username=&password=&cookieval=on&login=";
$username="";
$password="";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_FAILONERROR, 0);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_POSTFIELDS,$postFields);
curl_setopt($ch, CURLOPT_URL, $fullurl);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt"); # The name of the file containing the cookie data.
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
$returned = curl_exec($ch);
curl_close ($ch);
var_dump($returned);

Hi Guys,

I am learning PHP via Netbeans IDE in LinuxMint because it just feels closer to Visual Studio which I used in the past, i am trying to lean more with open source technologies.

I spin up a VirtualBox and installed apache2 on ubuntu.

I created the netbeans project from my linuxMint to the virtualbox apache2 server (remote server) and configured the virtual directories on the apache2 server. I can the test project successfully, however I cannot seem to debug via Netbeans like toggling a breakpoint to view variable values.

I found on the internet i need to configure xdebug and followed this site and used this page https://xdebug.org/wizard.php to create and install my xdebug.

I then updated my php.ini file to the following:

[xDebug]
zend_extension = /usr/lib/php/20170718/xdebug.so
xdebug.remote_autostart=on
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_host=192.168.56.1
xdebug.remote_connect_back=1
xdebug.remote_port=9000
xdebug.remote_mode=req
xdebug.idekey="netbeans-xdebug"

 

While my netbeans session id is configured "netbeans-xdebug" and debugger port to 9000. However, when i set a breakpoint in my code, netbeans seems to be stuck on "Waiting for connection" even it already passed the breakpoint. I suspect it's not even connected at all.

I do see from my host laptop (where I am running netbeans) that port 9000 does open when running the project with debug and ufw is turned off in both virtualbox machine and laptop.

 

Any ideas?
