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

Error Handling

Issue	Cause	Solution
Permission denied	Insufficient role	Request role upgrade from admin
SSO login fails	Wrong group mapping	Update group mapping config
API key rejected	Expired or scoped	Create new key with correct scope
Project not found	No access	Request project access from owner
