When using ldaps:// libldap will perform the TLS Handshake automatically before
sending the first LDAP request to the server. So calling ldap_start_tls_s() on
a ldaps:// connection is wrong and results in the above error.
ldap_start_tls_s is for initiating the TLS Handshake on a "normal" ldap://
See http://www.openldap.org/faq/data/cache/605.html for details.

If really want to use ldaps:// then specifying the ldaps:// URI in
ldap_initialize should be enough. Otherwise use a "ldap://" URI +
