Issues configuring SAML SSO for some customers

Issue Summary:

Beginning on December 5, 2019 at 11:45 a.m. PST, some Enterprise Grid Org Owners began having trouble configuring SAML SSO. A feature we recently implemented caused configuration requests to be registered as coming from unauthenticated users, even though these users were correctly authenticated. After deactivating this feature, full functionality was restored and the issue was resolved by December 10, 2019 at 12:57 p.m. PST.

11:19 PM PST

We’ve rolled out a fix and use of SAML SSO is back to normal. Please note that in order to see this fix, affected customers will need to log out and try logging in again from the beginning. Thank you for your patience while we sorted out this issue.

Some customers may be experiencing issues configuring SAML SSO. We are investigating and we're very sorry for the disruption.
