Outage in Slack
Trouble loading SSO configuration settings for some workspace admins
Resolved MinorIncident Report
Summary AI Generated
Slack's SSO and authentication configuration page failed to display current settings for admins on standalone (non-Enterprise Grid) workspaces, showing a blank "Require SSO authentication for" field for approximately 5.8 hours. Critically, actual SSO settings remained intact and enforced on the backend, meaning authentication was not broken — only the admin visibility into those settings was affected. Slack identified the root cause and deployed a fix to resolve the display issue.
Some workspace admins on standalone (non-Enterprise Grid) workspaces may be experiencing an issue where the SSO and authentication configuration page does not display current settings as expected. Admins may see a blank value for the "Require SSO authentication for" field on the admin SSO settings page, which does not accurately reflect the actual backend configuration — SSO settings remain intact and in effect.
We are actively investigating this issue and will provide an update as soon as we have more information to share. We apologize for the inconvenience.
