micsapp Langfuse Enterprise RBAC
Contents
Overview
Configure enterprise-grade access control for Langfuse with role definitions, scoped API keys, project-based access, SSO integration, and RBAC audit logging.
Prerequisites
- Langfuse organization/team account
- Understanding of role-based access patterns
- SSO provider (optional, for enterprise SSO)
Instructions
Step 1: Implement Role-Based Permissions
Define five roles (Owner, Admin, Member, Viewer, API Only) with granular permission maps for dashboard, traces, settings, members, billing, and data deletion.
Step 2: Create Scoped API Keys
Generate API keys with specific permission scopes, project restrictions, IP allowlists, and custom rate limits.
Step 3: Implement Project-Based Access
Build a project access controller that maps users to roles per project, with privilege escalation prevention.
Step 4: Integrate SSO
Map IdP groups to Langfuse roles via SAML assertions. Enforce email domain validation.
Step 5: Enable RBAC Audit Logging
Log all member additions, removals, role changes, and permission denials. Alert security team on denied access.
See detailed implementation for advanced patterns.
Output
- Role-based permission system (5 roles)
- Scoped API key management
- Project-level access control
- SSO group-to-role mapping
- RBAC audit trail
