If ldap_search() returns an error, it's unlikely that the request
was sent to the server. Hence, you'd likely not bother to call ldap_result()

Since you're toying with devel codes, you should read the ldap-c-api
I-D in the docs/drafts directory.

You should avoid worrying about socket
errors and just deal with LDAP result codes.
