  1. investigating Jun 16, 2025, 03:47 PM UTC

    We are currently investigating an authentication issue affecting some users logging in via OneLogin SSO at app.strongdm.com and the StrongDM GUI client. SAML: A recent change from OneLogin appears to impact SAML logins. As a workaround, remove the trailing slash from the Login URL in your StrongDM application settings within OneLogin. This restores login functionality for most SAML users. OIDC: A recent change from OneLogin appears to impact OIDC logins. OneLogin has reverted the change. No further action is required.

  2. investigating Jun 16, 2025, 05:46 PM UTC

    We are continuing to investigate this issue.

  4. resolved Jun 16, 2025, 05:55 PM UTC

    This issue has now been resolved. SAML: The app login URL should not include a trailing slash. OIDC: OneLogin reverted the changes to OIDC authentication behavior, no further changes are required.
