So, I'm attempting to set up adLDAP with SSO. $SERVER['RemoteUser'] is being set correctly (getting the Username of the windows log in.) However, when I attempt to do anything with adldap, such as checking if the windows user is in a group , I get the following error:

Notice: Undefined index: KRB5CCNAME in C:\xampp\htdocs\bmraWebClient\externals\adLDAP\src\adLDAP.php on line 654

I am using: Apache v2.4, PHP 5.6.8 on Windows Server 2008.
