langfuse SSO

### Langfuse SSO Integration Guide #### Overview of Single Sign-On (SSO) Single Sign-On (SSO) allows users to access multiple applications and services using a single set of credentials, enhancing both security and user convenience. For integrating SSO into platforms like Langfuse, the process involves configuring authentication mechanisms that can securely verify user identities across different systems. Langfuse supports various methods for implementing SSO through third-party identity providers or custom solutions depending on specific requirements[^1]. #### Prerequisites for Integrating SSO with Langfuse Before starting the integration: - Ensure an active subscription plan supporting advanced features such as SSO. - Obtain necessary details from your Identity Provider (IdP), including metadata URL, entity ID, etc. - Decide which protocol will be used—commonly OAuth 2.0, OpenID Connect, or SAML 2.0—for communication between Langfuse and IdP. #### Configuration Steps within Langfuse Platform To configure SSO inside Langfuse: Navigate to **Admin Settings**, select **Security & Authentication**, then choose **Single Sign-On** option where one could specify settings related to chosen protocols mentioned earlier. Afterward, input relevant information provided by IdP according to selected standards. For instance, when opting for SAML-based setup: ```xml <samlp:AuthnRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol" ID="_abcde..." Version="2.0"> <!-- Other elements --> </samlp:AuthnRequest> ``` Or if preferring OIDC flow: ```json { "client_id": "...", "redirect_uris": ["https://yourapp.com/callback"], ... } ``` After completing configuration changes, test thoroughly ensuring seamless interaction without errors during login attempts via external IdPs. #### Troubleshooting Common Issues During Setup If encountering issues while setting up SSO functionality: - Verify network connectivity is stable since intermittent disruptions may cause failures in obtaining tokens required for successful logins. - Check expiration status of any involved tokens; clearing caches followed by re-authentication might resolve temporary glitches caused by stale data [^2]. - Confirm consistency among all configured endpoints regarding supported protocols preventing mismatches leading to unsuccessful authentications. By following these guidelines carefully, organizations should achieve smooth implementation of robust SSO capabilities tailored specifically towards their needs utilizing Langfuse's flexible infrastructure. --related questions-- 1.
