Remote authentication module allowing for single sign-on between Zendesk and Drupal-supported sites, so that users logged into your site are automatically logged into your Zendesk.
How to install
Set up is simple. Visit http://drupal.org/project/zendesk to download the module.
Once downloaded, install into your Drupal environment.
Log into your Zendesk account as an administrator and navigate to Manage -> Security.
Locate the Single Sign on section and check the Enabled box.
Select the Mode as Zendesk Remote Auth
Enter the Remote Login URL as
http://yoursite.com/services/zendesk (replace yoursite with your own website).
Optionally, you can insert a logout URL as well under the Remote Logout URL
Make note of the Shared Secret that is generated in Zendesk.
Back in Drupal, navigate to admin/config/people/zendesk and fill in the URL of your Zendesk support page (e.g. http://yourdomain.zendesk.com) together with the Shared secret key that you obtain from the previous step.
