    Bug Description: TLS not working with latest openldap
    Reviewed by: nkinder (Thanks!)
    Branch: master
    Fix Description: The previous fix did not take into account ssl client
    auth.  The way openldap ssl init works now is that you must set all of the
    ssl parameters before creating the new ctx.  Since slapi_ldap_init_ext()
    does not know if client auth will be used, we have to do all of the ssl
    init in slapi_ldap_bind.  Doing setup_ol_tls_conn() again will free the
    old TLS context and parameters.  It is a little more time consuming in
    the clientauth case, but is safer and saves time in the other cases.
