Installation

LDAP support in PHP is not enabled by default. You will need to use the --with-ldap[=DIR] configuration option when compiling PHP to enable LDAP support. DIR is the LDAP base install directory. To enable SASL support, be sure --with-ldap-sasl[=DIR] is used, and that sasl.h exists on the system.

Note: Note to Win32 Users

In order for this extension to work, there are DLL files that must be available to the Windows system PATH. For information on how to do this, see the FAQ entitled "How do I add my PHP directory to the PATH on Windows". Although copying DLL files from the PHP folder into the Windows system directory also works (because the system directory is by default in the system's PATH), this is not recommended. This extension requires the following files to be in the PATH: libeay32.dll and ssleay32.dll
Versions before PHP 4.3.0 additionally require libsasl.dll.

In order to use Oracle LDAP libraries, proper Oracle environment has to be set.

I found not only "Versions before PHP 4.3.0 additionally require libsasl.dll.".

If you use php-5.3.3-Win32-VC9-x86 or later Versions that
It's require libsasl.dll.

Running under Windows & Apache 2.2.8
PHP file is download from http://windows.php.net/downloads/releases/archives/

When I use php-5.2.x-Win32-VC6-x86 and php-5.3.x-Win32-VC6-x86

1.just uncomment extension=php_ldap.dll  in php.ini
2.Restart apache,it's ok

When I use php-5.3.x-Win32-VC9-x86 and php-5.4.x-Win32-VC9-x86

1.just uncomment extension=php_ldap.dll  in php.ini
2.Restart apache,always fail...
(only php-5.3.1-Win32-VC9-x86 & php-5.3.2-Win32-VC9-x86 is ok. )

[php-5.3.3-Win32-VC9-x86 or later Versions]
1.just uncomment extension=php_ldap.dll  in php.ini
2.copy  libsasl.dll to [apache folder]\bin
3.Restart apache,it's ok

If using a debian machine (debian or ubuntu variants) just do apt-get install php5-ldap, that's all to get ldap work on php. No need to get sources, try to compiling them and  so on.

To enable PHP LDAP for IIS, I installed PHP Manager which integrates with IIS. Open this up and you can enable/disable extensions. Enable php_ldap.dll and it works straight away.

Users of the "WAMP Server" software need to enter PHP's path... as the documentation says. Although apache\apache[...]\bin\ also contains the files mentioned, this does not suffice for some reason.
For me, the path is C:\wamp\bin\php\php5.5.12

If you're running on Windows XP with Apache, and you installed PHP 5 from the windows installer rather than the full zipped version - you may not have the php_ldap.dll file.  



I had to follow the steps above, making sure PHP was added to my Windows Path, adding the 2 dll files to the system32 directory, also making sure the php.ini extensions directory was set correctly (in my case: C:\Program Files\PHP\ext).  



Still was a getting a message about not being able to locate the "php_lamp.dll" file.  I finally went back, downloaded the full .zip file of latest PHP version, and that missing dll file is included there - along with many others.  



Remember to restart Apache server after you do all this.

The easiest way to install ldap extension on Ubuntu 12.04 is:

sudo apt-get install php5-ldap

Also don't forget to laod the extension.

OCI client from Oracle distributes un ldap.h which may collision with the SO ldap.h.
You can, remove the Oracle ldap.h and build or configure php without oci8 and then add OCI8 later as a shared extension.
This latter step is easiest using PECL: pecl install oci8. You will then need to add 'extension=oci8.so' to your php.ini.

Running under IIS, I found php_ldap would not load even though d:\php contained libeay32.dll and ssleay32.dll, and d:\php was in the PATH environment variable.

I finally tracked this down to the position of d:\php in the PATH.  If d:\php is near the head of the PATH, everything works fine.  If d:\php is near the end of the PATH, apparently it gets ignored by IIS (even though it works fine from the command line, e.g., with php -m).  Have no idea why this is.

It seems that the php 5.3 windows installer does not install the ldap.dll to the hard drive as standard - during the install process i had to specifically request that it was installed.

I can confirm Frank's note (made 1 year ago, see below) about requirement of "libsasl.dll" library. I have "PHP Version 5.4.7" and my Apache fails to restart with error saying, that "libsasl.dll" is missing, once I enable php_ldap.dll extension in PHP configuration.

What is even more strange, I DO HAVE this library (along with required "ssleay32.dll" and "libeay32.dll" in my PHP's directory and my PHP's directory IS listed in Windows' PATH variable and even so, I'm facing the problem of Apache failing to start.

The only workaround, I found is to copy "libsasl.dll" to "system32" system directory. Solution, that PHP documentation here discourages.

So, to summarize, section "Note to Win32 users" is twice wrong. You DO have to have "libsasl.dll" directory and you have to place it in your system folder.

Sorry - I was referring to "php_ldap.dll", not php_lamp.dll

Running under IIS, I did not find the need to download and compile libraries.

1. Edit PHP.INI (which should be in windows directory)
2. Uncomment the line extension=php_ldap.dll
3. Restart IIS
