Resolved MinorIncident Report
Summary AI Generated
MongoDB Atlas for Government experienced SSO login failures due to an SSO routing issue that prevented some users from accessing the UI via saved SSO URLs or federated identity provider links, with affected users encountering 400 errors or incomplete authentication flows. The incident lasted approximately 13 days starting March 18, 2026, and was resolved after implementing a fix to restore full SSO login functionality. Users were able to work around the issue by logging in directly through the standard email prompt at the MongoDB Government account portal.
Impact: Some users may be unable to log into the Atlas for Government UI using SSO. Specifically, users accessing Atlas for Government via a saved SSO login URL may receive an error, and users attempting to log in via a federated identity provider link may be unable to complete authentication.
Root cause: We have identified an issue with SSO routing that is preventing some federated login flows from completing successfully. These issues started around 2026-03-18 2:30 UTC.
What you might see:
- A 400 error when navigating to Atlas for Government via a bookmarked or direct SSO URL.
- An inability to complete login when using a federated identity provider link.
Our actions: A fix is being implemented. Actively working to restore full SSO login functionality for affected users.
User action: As a workaround, users can log in by entering their email address directly at https://account.mongodbgov.com and following the standard prompts. If you have time-sensitive changes that are blocked and need urgent assistance, please contact MongoDB Support.
