Error using WAMP with LDAP - php

Question

I'm using WAMP and trying to run something like the following:
<?php
$ldap = ldap_connect("ldap.example.com");
$user = "exampleUser";
$pass = "examplePass";
if($bind = ldap_bind($ldap, $user, $pass)) {
// logged in
} else {
// error message
}
?>
Before doing this though, I tried running phpinfo() to see if ldap was installed, and it doesn't appear anywhere.
I've tried the following:
Uncommented the following line in php.ini: extension=php_ldap.dll
Copied these files into the same directory as php.ini: ssleay32.dll
and libeay32.dll
Added the following to my environment variables: C:\wamp\bin\php
Restarted after doing any of these.
I don't really know what I'm doing, but these were the suggestions I found online. Any help would be appreciated!

Answer 1

This answer may be useful for others who come across this question as it's over a year since the OP posted this question.
I'm running
WAMP Version: 2.4
Apache Version: 2.4.4
PHP Version: 5.4.16
I tried most suggested solutions that a Google search will bring you to and nothing seemed to work. A forum recommended looking at the PHP pages
A user by the name of Frank in the above link recommended to copy libsasl.dll to [apache folder]\bin despite this only being recommended for earlier versions of php, this file is in the php folder.
copy "C:\wamp\bin\php\php5.4.16\libsasl.dll" "C:\wamp\bin\apache\apache2.4.4\bin\libsasl.dll"
This is what worked for me and LDAP is now showing up when I use phpinfo(), although I haven't properly tested it yet besides running the ldap_connect() function, but I'm assuming that means it is working and I should be able to use it in my application.
Besides adding libsasl.dll to the Apache bin I added C:\wamp\bin\apache\Apache2.4.4\bin and C:\wamp\bin\php\php5.4.16 to my PATH (i.e. the Windows environment variables -> system variables -> path) and I added ssleay32.dll and libeay32.dll to the both the Apache and php bin, not sure if required but it's working now.

Answer 2

What errors do you get? function does not exist?
Also you should add the following lines after your ldap_connect function:
ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldap, LDAP_OPT_REFERRALS, 0);
ldap_set_option($ldap, LDAP_OPT_DEBUG_LEVEL, 7);
if(!$ldap){
echo "LDAP Failed To Connect: ".ldap_error($ldap);
}
The options set ldap to protocol version 3, which is needed for active directory and alike on server 2k3 and alike and enabled debugging on the ldap connection.
Update
Also, run phpinfo() and look for the extensions directory. Navigate to that directory and make sure that php_ldap.dll exists in there.

Answer 3

I simply copied 'libsasl.dll' from the php directory to the apache directory and obviously restarted httpd. This solved my problem.
This was not a WAMP installation, I installed apache and php separately. Perhaps in case of WAMP or LAMP some more files can be needed.

Answer 4

I resolved the same problem by adding the php folder in the following Windows system path:
at command prompt
SET PATH=C:\wamp\bin\php\php5.3.13;%PATH%

Answer 5

it's very too late, but i had the problem and i wanted to add that you must uncomment extension=php_ldap.dll in both php and apache's php.ini.
