Hello,
The problem doesn´t seems to be in PHP. It´s a problem with the LDAP
and SASL.
From the bug-database:
When you use OpenLDAP 2 or other libraries that use the
new LDAP API, ldap_connect() will only create some state
on the client, the server is not contacted until you later
do an LDAP operation like search or bind. There are no DNS
lookups either, so ldap_connect("jlkdsfjsdk") will be
successful. This means that ldap_connect() will almost
always return true, while later operations might very well fail.
Another difference worth noting, is that for anonymous
access there is no more need for ldap_bind(). You just
do your search.
This thread can be closed.
Thanks and greetings
Alexander

No need to shout here and how do you expect us to reproduce the problem
without an LDAP server?

Cannot reproduce with my ldap servers, the specified
hostname for your ldap server cannot be resolved.

Description:
------------
A Login make a request to LDAP-Server for User-Authentication.
The code is very simple, but it doesn´t work on Linux.
ldap_connect works fine on both (Windows and Linux)
ldap_bind anonymous works NOT on Linux! But on Windows works!
What´s the problem?
Reproduce code:
---------------
<?php
$ldaphost = "ldapserver.diedler.com";
$ldapport = 389;
// Verbindung zu LDAP
$ldapconn = ldap_connect( $ldaphost, $ldapport );
if ($ldapconn) {
echo "<li>It works!<br>";
}else {
echo "<li>Failed<br>";
}
$ldapbind = ldap_bind($ldapconn);
if ($ldapbind) {
echo "<li>anon. Bind works!<br>";
}else {
echo "<li>bind failed<br>";
}
?>
Expected result:
----------------
The same result like on windows. It should work fine!
Actual result:
--------------
I removed all packages from Linux with PHP and Apache and LDAP.
I installed Apache 1.3.28 with devel.
OpenLDAP Client V2 and ldap_devel.
PHP 4.3.8 from Homepage php.net.
Install with ./configure --with-mysql --with=apxs --with-ldap
Important: remember that the connect to LDAP Server works! So it is not
a maschine problem!
