Kafka LDAP Authorizer

Important

This is a Confluent Enterprise-only feature.

Kafka LDAP authorizer enables group-based authorization using the principal type Group as well as user-principal-based authorization using the principal type User. If a Deny rule matches the user principal or any of the groups that the user belongs to, access will be denied. Otherwise access is allowed if an Allow rule matches the user principal or any of the groups that the user belongs to. The configuration option allow.everyone.if.no.acl.found can be set to true to allow access if no ACLs match the user or groups. Super users or super groups with access to all resources can be configured using the configuration option super.users. This may contain user principals as well as group principals. For example:

super.users=User:kafkaBroker;Group:admin

Kerberos users with LDAP servers that provide Kerberos authentication as well group management can use the same LDAP server (e.g. Active Directory or Apache Directory Server) for both authentication and group-based authorization. Brokers using other security protocols or SASL mechanisms may also use group-based authorization using LDAP without using the LDAP server for authentication.
