    oh, boy. this one is going to be fun to debug….

    to get to line 491, you would have had to have a valid return (non boolean false) at line 490 for
    $results = @ldap_search($connection, $baseDn, $filterQuery, $returnKeys)) !== false

    A return of false would indicate a failure from ldap_first_entry and not just an empty return set.

    Is there anything else in your logs that might shed some light on why the call to ldap_first_entry failed?

    Can you try running this script (and adding in the necessary info) https://github.com/gilzow/simple-ldap-test/blob/master/ldap.php on your instance to help debug ?
