Unable to enable PHP LDAP even though I have edited php.ini and php_ldap.dll is in the right place?

I've been working with a WAMP install for quite a while now with LDAP enabled and everything is going smoothly. Now though I have to set up another machine and for some reason I can't enable LDAP.

I checked the output of phpinfo() and the LDAP section isn't there. I edited php.ini to uncomment the line:

extension = php_ldap.dll

I also checked the filepath being searched for extensions and the file php_ldap.dll is in the right place.

I'm positive I'm editing the right php.ini file since I checked the filepath being shown by phpinfo(), and also I am able to successfully enable/disable other extensions.

I have rebooted Apache after every change made.

While Googling this, the only solutions I found were those above, plus one or two mentions of editing the Windows PATH variable to include the path to php.ini? Tried it even though it didn't make sense to me (as I already know php.ini is being parsed). I also checked my previous install on the other machine and from what I can see I never added any PHP directories to the PATH on that machine

Edit with complete answer

Frank's answer below led me to the solution so I thought I'd consolidate everything now.

To Enable LDAP Support on a WAMP server:

  1. Uncomment extension = php_ldap.dll in php.ini
  2. IMPORTANT: Make sure that you're editing the right php.ini by checking the output of phpinfo()
  3. Check the php.ini file for the location of your extensions directory
  4. Check that php_ldap.dll is located in that directory
  5. (THE STEP I MISSED) Find the files libeay32.dll and ssleay32.dll and add their directory to the Windows PATH
  6. Reboot Apache. If LDAP is enabled there will be a section about it in the output of phpinfo()

There are a few hints here: http://php.net/manual/en/ldap.installation.php . Note you need to add two other DLLs libeay32.dll and ssleay32.dll. You may also need to compile with --with-ldap
