After setting up Split SSO integration with GSuite, when trying to login, getting 403 HTTP error, and page go back to Split login page.
There are two possible root causes:
- In GSuite setup page, "ACS URL" field does not match "Entity ID" field.
- "Signed Response" box is checked
- Make sure the "ACS URL" field is identical to "Entity ID" field.
- Make sure the "Signed Response" is unchecked.
