Authentication check​

Atlan validates the authentication method configured for your Trino connection:

Basic authentication​

  • ✅ Username and password validation: Verifies that the provided credentials are valid and have the necessary permissions to access Trino catalogs and schemas.

JWT authentication​

  • ✅ JWT token validation: Verifies that the provided JWT token is valid, not expired, and contains the required claims.
  • ✅ Claims validation: Ensures the JWT token contains the necessary claims for Trino authentication.

❌ Authentication failed: The provided credentials or JWT token are invalid, expired, or lack the necessary permissions.
