WordPress.org

1. Login as an existing user, such as admin.
2. Upload the folder named simple-ldap-authentication to your plugins folder, usually wp-content/plugins.
3. Activate the plugin on the Plugins screen.
4. Enable the "Admin SSL" plugin (or anything that redirects the logon page to an SSL connection) so that your passwords are not sent in cleartext.
   • If the version of Admin SSL is 1.4.1, you should apply the redirection bug patch.

Note: This plugin has only been tested with WordPress 2.7.1 and above, and I do not think it will work on older versions of WordPress.
