There are a few simple changes that are needed to compile with SSL/TLS support
in libldap.  Once these are changed, and ldap.conf is set up properly (and the
LDAP server is set up to support SSL/TLS, and you've compiled with openssl or
ssleay, etc.), secure connections work quite nicely.  There remain the issues of
verifying the server certificate and doing client certificate authentication.
