I am trying to bind to an LDAP server using php without success. I have a linux server running php compiled with open ldap. I am using the following code taken right from php.net: -
echo "<h3>LDAP query test</h3>";
-
echo "Connecting ...";
-
$ds=ldap_connect("ldap.berkeley.edu"); // must be a valid LDAP server!
-
echo "connect result is ".$ds."<p>";
-
-
if ($ds) {
-
echo "Binding ...";
-
$r=ldap_bind($ds); // this is an "anonymous" bind, typically
-
// read-only access
-
echo "Bind result is ".$r."<p>";
I get a result from ldap_connect, but an error with ldap_bind. I get the following error:
Warning: ldap_bind() [function.ldap-bind]: Unable to bind to server: Can't contact LDAP server in /home/eric/public_html/academic-senate-test/authenticate/login_action.ph p on line 26
I can access ldap.berkeley.e du from other ldap browsers just fine. The php code is on a server separate from the ldap directory. Is there a specific way to compile php with ldap so that it knows to access a server that is not local, could this be the problem?
I have googled, found a fair number of people reporting this problem but no answers. I appreciate any advice, thanks!

Heya, Eric. Welcome to TSDN!
Changed thread title to better describe the problem (did you know that threads whose titles do not follow the Posting Guidelines actually get FEWER responses?).
Please use CODE tags when posting source code:
[CODE=php]
PHP code goes here.
[/CODE]
Thanks for the posting guidelines.
Here is the readout from phpinfo under the ldap section:
LDAP Support enabled
RCS Version $Id: ldap.c,v 1.161.2.3.2.11 2007/07/17 09:09:42 jani Exp $
Total Links 0/unlimited
API Version 3001
Vendor Name OpenLDAP
Vendor Version 20213
Appreciate any advice, thanks!

Heya, Eric. Welcome to TSDN!
Are you sure your LDAP server allows anonymous connections?
Try using the ldap_error() function to see if you can find any more details on the error.

Hello,
Here is my situation. I have developed several apps that require
authentication to access. For authentication, I have the users enter thier
user/pass and click login, which is then sent to an LDAP Server (NOVELL) - if
binding is successful, I use the login object to retrieve various
fields/attributes of the LDAP directory for that user.
This works just fine, but what I want to do is transparently log the user in

I'm trying to bind to DC by site. The environment is a AD 2K3 domain with
multiple sites.
For example, when my application is started, it checks for the site of the
computer where the application is running. Then, it looks for a DC in the
site and then all DirectorySearcher and DIrectoryEntry operations will use a
binding string aimed at that DC on the site.
If the DC is not available, then a default server, the PDC emulator is used.

Hi,
I have a basic script for querying an ldap server. It works fine from
my college's production server, but not from another server in the
network, though I have been assured access should be allowed from
there.
It fails at the ldap_bind() function. This function only returns a
boolean value. How might I retrieve a meaninful error message? Any
ideas where the problem is likely to lie, with this basic info?

I'm trying to troubleshoot an issue where users are not able to bind
with LDAP via "GetObject" through our ASP Classic Intranet if they
stay logged in overnight (beyond their allowed login hours). The
problem does not occur when performing the same bindings using a logon

So, the user logs in, is able to perform queries all day, and then
fails to log out at the end of the day. We'd prefer that they did log
out nightly, but it...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
