+** This method should be used in preference to SSL_ConfigSecureServer,

+**
+** The optional |data| argument contains additional information about the

+**
+** - |authType| (with a value other than ssl_auth_null) limits the
+** authentication method; this is primarily useful in limiting the use of an
