Live Lookup AD Not Filtering Results

I have used the sample php file provided by Helpspot to interface with AD at our organization. It appears to be communicating properly, however, when performing a live lookup it lists every single user no matter which field I use (first name, last name or email address). Is there something that needs to be modified in the php file to filter the results? Does anyone have an example of their php script that they can post. I only need to search by first name, last name or email address. Thanks in advance.
