Single Sign-On/SSO for Drupal 8

Single Sign-On for Drupal is a professional extension that automatically creates accounts and signs users in as they browse between multiple and independent Drupal websites in your network. Take away the need for your users to create accounts or re-enter their authentication credentials when they switch from one of your websites to another.

This extension requires a OneAll site with an enterprise plan that includes the Single Sign-On service.

d. Setup Single Sign-On on your other websites

Now repeat the installation for each of your Drupal websites. Single Sign-On will automatically create accounts and sign users in as they browse between multiple and independent websites, databases and domains. The plugin is fully compatible with our other Single Sign-On plugins like per example for WordPress or OpenCart.

3. Troubleshooting

a. The API communication does not seem to work correctly

Please make sure that your firewall does not block outbound requests on both ports 80 and 443. One of these ports must allow outgoing requests (from your server to ours) so that the plugin can establish a communication with our API.

If you have access to the console of your server you can test if outbound requests are allowed by using this command: telnet ping.api.oneall.com 443. If the port is open then you should obtain a result like this:

		~$ telnet ping.api.oneall.com 443
		Connected to ping.api.oneall.com.
		Escape character is '^]'.

b. You are not authorized to access this page

If you encounter this error when Single Sign-On tries to log you in, then you might have installed a Drupal module (e.g. Security Kit) which blocks offsite POST requests from our API to your server. To fix the issue please whitelist the following domain for offsite requests:
