Incident Report

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.
