SSO login failures for the published Harness Okta application

Resolved after 2 days 4 hours, on September 29, 2026.

identified Sep 29, 2026, 08:57 PM UTC

We identified an issue that applies only to SP-initiated login through the published Harness Okta application. After a recent update to that application, those login attempts returned an HTTP 400 error when the configured SSO URL was missing from Additional ACS URLs. General SAML 2.0 configurations in Okta are not affected. Immediate Solutions: Use IDP-initiated login. Start the login from the Harness application tile in Okta. Or Add your Harness SSO URL to Additional ACS URLs in the published Harness Okta application.
