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.

1. Log in to Flexera One.
2. Navigate to Administration > Identity Providers > Domains.

3. Select Add a Domain and follow the prompts.
4. 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.
