When attempting to use Okta’s single sign-on (SSO) to log into Flexera One, some users may encounter a “400 Login Failed” error. This error can occur if Okta is attempting to authenticate with a domain that has not been verified in Flexera One. Flexera One requires validation of each domain used for SSO to ensure the security and integrity of the authentication process. When a domain is not properly validated, Okta rejects the request, resulting in the error.
Solution
To resolve the Okta “400 Login Failed” error, follow the steps below.
- Log in to Flexera One.
- Navigate to Administration > Identity Providers > Domains.
- Select Add a Domain and follow the prompts.
- Save the changes to the identity provider settings.
Try the SSO process again to verify the issue has been resolved.
NOTE: To avoid encountering the Okta “400 Login Failed” error due to an unvalidated domain, validate any new domains before attempting to use them for SSO.
