also returns an error if you pass it an ldap link identifier, which is a
resource. Careful.

In the page that describes the resurce data type, there is a comment posted
that says that ldap-connect does not return a resource, as it might be
expected, but an integer. That would be the reason that you get an error
when using get_resource_type() on a ldap "resource"
