+ /* Setup:
+ * - Create or edit the file data/host.data and add an
+ * ldap server DN. Multiple DNs may be listed on
+ * a single line.
+ * - Copy the server certificates to the data/ directory.
+ * All DER type certificates must have the .der extention.
+ * All BASE64 or PEM certificates must have the .b64
+ * extension. All certificate files copied to the /data
+ * directory will be added to the ldap certificate store.
+ */
+
+ /* This test covers the following three types of connections:
+ * - Unsecure ldap://
+ * - Secure ldaps://
+ * - Secure ldap://+Start_TLS
+ *
+ * - (TBD) Mutual authentication
+ *
+ * There are other variations that should be tested:
+ * - All of the above with multiple redundant LDAP servers
+ * This can be done by listing more than one server DN
+ * in the host.data file. The DNs should all be listed
+ * on one line separated by a space.
+ * - All of the above with multiple certificates
+ * If more than one certificate is found in the data/
+ * directory, each certificate found will be added
+ * to the certificate store.
+ * - All of the above on alternate ports
+ * An alternate port can be specified as part of the
+ * host in the host.data file. The ":port" should
+ * follow each DN listed. Default is 389 and 636.
+ * - Secure connections with mutual authentication
