Platform: Global - SAML/Federation Authentication Failures

Update timeline

1. resolved Apr 10, 2026, 04:11 AM UTC

   This incident has been resolved. SAML/Federation authentication has been fully restored for all affected tenants. A platform update deployed earlier today introduced a change that caused login failures for tenants with non-default SAML issuer settings. We apologize for the disruption and will be publishing a full post-incident review. Investigating We have received reports of SAML/Federation users being unable to log in to their Delinea Platform tenants. We are actively investigating the issue and will provide updates as more information becomes available. Tenants using username/password authentication are not affected at this time.

   ### Incident Overview On Friday, April 3rd, 2026, a subset of SAML/Federation users were unable to authenticate to their Delinea Platform tenants. The issue was first reported at approximately 5:01 PM ET and was fully resolved by 8:38 PM ET following a rollback of a recent platform update. Tenants using the default SAML issuer configuration were not impacted. Customers with local \(non-SAML\) accounts retained access throughout the incident via breakglass or local admin credentials. ### Root Cause A platform update deployed at approximately 4:20 PM ET introduced a code change that inadvertently caused custom SAML authentication configurations to not be correctly applied for affected tenants. This resulted in authentication failures for tenants that relied on a custom SAML issuer, while tenants using default settings were unaffected. A contributing factor was insufficient test coverage for this specific authentication scenario prior to the global rollout of the update. ### Preventive Actions * A code fix is being implemented to ensure custom SAML authentication configurations are correctly applied in all cases going forward. * Automated test coverage is being expanded to include SAML authentication scenarios with custom configurations to prevent similar issues in future releases.
