Description:
------------
Ldap_connect does not work.. tcpdump shows no traffic on the network when trying to connect..

>dpkg -s |grep ldap gives:
ii  ldap-utils     2.1.23-1       OpenLDAP utilities
ii  libldap2       2.1.23-1       OpenLDAP libraries
ii  libldap2-dev   2.1.23-1       OpenLDAP development libraries

The compile went fine and ldap show up as expected in phpinfo()
LDAP Support 	enabled
RCS Version 	$Id: ldap.c,v 1.151 2004/04/06 23:14:06 iliaa Exp $
Total Links 	0/unlimited
API Version 	2004
Vendor Name 	OpenLDAP
Vendor Version 	20123


I have compiled with the following directives:
'./configure' '--with-mysql' '--with-apxs' '--with-gd' '--with-openssl' '--with-zlib' '--enable-bcmath' '--enable-calendar' '--with-curl' '--enable-dio' '--enable-ftp' '--with-ttf' '--enable-gd-native-ttf' '--with-kerberos' '--with-imap-ssl' '--with-mcrypt' '--enable-embedded-mysqli' '--enable-soap' '--with-xsl' '--with-pear' '--with-ming' '--with-oci8' '--with-ldap'

Reproduce code:
---------------
<?php
$connect = ldap_connect($server);
if ($connect) {
    echo "Connected OK - That is the server ($server) is     }else {
    echo "Connect FAILED server=($server)";
}
?>

Expected result:
----------------
I want to get a valid ldap connection, like I do when I run the script on another server with PHP4..



Actual result:
--------------
ldap_connect() just returns null...
Nothing is ever sent on the network..

The reason nothing is sent over the network has to do with how the OpenLDAP library handles "connections".  Even under the best cirsumstances an ldap_connect() doesn't actually contact the remote server until you reach the ldap_bind() stage.

Of the reasons ldap_connect() would return false, the only one which does not generate an error message is a specific form of initialization error, can you check your main/php_config.h file for a line containing LDAP_API_FEATURE_X_OPENLDAP and paste any lines containing it (plus a couple above/below for context)?

ldap_connect() never returns NULL however, are you certain that's what you're getting back and not FALSE?

Well actually ldap_connect returns false and not null..
Also there may be a resonable explanation that it does not send anything on the network.. But
How can it be that I do not get a valid handle then (as it cannot determine whether it can or cannot connect to the server without trying).
The script works fine on another server running php4.
 [2004-06-04 15:10 UTC] thu at nykredit dot dk 
main/php_config.h does not contain a line like: "LDAP_API_FEATURE_X_OPENLDAP"..
I have not changed anything in this file - it is the original file from RC2..
 [2004-07-02 11:28 UTC] thu at nykredit dot dk 
It works with PHP5 RC3 on a Fedora 2... 
So.. something with my debian installation must have caused the trouble, or the error have been fixed...
