title: Cannot get LDAP extension enabled on new PHP IIS server
body: <p>I have a new server at work, installed PHP 5.4.21 on it yesterday, got SQLSRV working this morning but now I'm stuck getting LDAP enabled. It's not showing in phpinfo(). This is my php.ini file that is in C:\PHP which is where phpinfo() says is the correct directory: <a href="http://pastebin.com/yWv9gRNT" rel="nofollow">http://pastebin.com/yWv9gRNT</a></p>
  
  <p>I have uncommented <code>extension=php_ldap.dll</code> (near the bottom), I have the dll in the ext folder that is linked in the php.ini file, I have restarted IIS numerous times, I have even copied all DLLs to Windows\System32 folder as recommended on some forums (including libsasl.dll libeay32.dll &amp; ssleay32.dll) &amp; restarted server. Server is Windows 2008 R2 running IIS 7.5.</p>
