OAuth 2.0, LDAP, and HTTP auth for Amazon MQ for RabbitMQ
Big Data Blog
This article explains three authentication and authorization integrations for Amazon MQ for RabbitMQ that eliminate the need for broker-local credentials.
- OAuth 2.0 provides token-based authentication using short-lived JWT tokens validated via JWKS endpoints with scope-to-permission mapping
- LDAP connects the broker to directory services like Active Directory for centralized user management and group-based permissions
- HTTP authentication backend delegates all auth decisions to an external HTTPS service for custom identity integrations
- OAuth 2.0 scopes map to RabbitMQ permissions (read, write, configure) across vhosts and resources
- LDAP uses group-centric directory structure with separate OUs for vhosts, exchanges, queues, and management tags
- HTTP backend requires HTTPS endpoints and supports caching to reduce load on the authentication service
- All three approaches require encrypted connections and provide centralized access control through existing identity infrastructure
These authentication methods enable enterprise-grade security by integrating Amazon MQ with OAuth 2.0 providers, LDAP directories, or custom HTTP services.
