UPDATE:2/28/19 Upcoming DocuSign SSO certificate renewal
On Monday March 4th, 2019 at approximately 4:00 PM PST DocuSign will replace their Single Sign-On certificate and simultaneously change the CA in all production environments. At that time DocuSign will only sign outbound SAML requests with a single certificate, the new certificate. Please take immediate action to update the SSO certificate and/or metadata URL within your IdP application as needed to prevent user login issues. If you are unsure how to complete these steps please contact your IdP.
