/* 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
