You can use this feature to prevent SSO into your Shopify store based on IDP attributes.
You can specify which users with specific attribute values are allowed or denied access to your Shopify Store by creating rules. You could, for example, create a rule that prevents users with a specific tag or domain from accessing certain parts of your Shopify Store.
Navigate to Apps >> miniOrange Single Sign On – SSO application.
Now go to the Setup IDP section.
Navigate to the Additional Settings section in the application dashboard and enable the Block SSO based on attributes from the IDP option.
Click on the + icon and add an attribute as shown in the below image.
If the attribute name from IDP matches the blocked attribute value, the user will be redirected to the blocked page after they SSO into the Shopify Store.
Click on Save.
For example, if the Blocked attribute name is “domain” and its value is “@gmail.com”, then all customers with a @gmail domain will be redirected to the blocked page after they perform SSO to the Shopify Store.
