🆕 New Feature
✅ Test

Changes

• Default behavior: AUTO_REDIRECT_UI_LOGIN_TO_SSO now defaults to false instead of true. When SSO is configured, users see the login form by default instead of being automatically redirected to SSO.
• Login with SSO button: Added a "Login with SSO" button on the login page. When SSO is configured, the button navigates to the SSO flow. When SSO is not configured, the button is disabled and shows a popover prompting the user to configure SSO.
• Discovery endpoint: The /.well-known/litellm-ui-config endpoint now includes sso_configured so the UI can conditionally render the SSO button.
• Tests added for the new default and the Login with SSO button behavior.

Greptile Overview

Greptile Summary

Changes the default login behavior so users see a login form instead of being auto-redirected to SSO. Adds a "Login with SSO" button to the login page that is enabled when SSO is configured and disabled (with a popover hint) when it's not. The /.well-known/litellm-ui-config discovery endpoint now exposes sso_configured so the UI can conditionally render the button. AUTO_REDIRECT_UI_LOGIN_TO_SSO now defaults to false.

• Breaking change: AUTO_REDIRECT_UI_LOGIN_TO_SSO default flipped from true to false — existing deployments relying on auto-redirect will need to explicitly set this env var to true
• New sso_configured field added to UiDiscoveryEndpoints model and the corresponding TypeScript interface
• Login page conditionally renders an enabled or disabled "Login with SSO" button based on sso_configured
• Tests added for both backend (new default behavior test) and frontend (SSO button enabled/disabled states)

Confidence Score: 4/5

• This PR is safe to merge; the only risk is the breaking default change for existing SSO users.
• Clean, well-tested feature with no logic bugs. Score of 4 (not 5) because the default change for AUTO_REDIRECT_UI_LOGIN_TO_SSO is a breaking behavior change that could impact existing deployments relying on auto-redirect — this should be clearly communicated in release notes.
• No files require special attention from a code correctness standpoint.
