Enable RBAC

You can enable role-based access control (RBAC) on a Confluent Platform deployment that was originally configured without RBAC enabled.

Set the following and provide the required properties for RBAC in your hosts inventory file:

rbac_enabled: true

For a list of all the RBAC-related properties and their, refer to Role-based access control.

Below is an example snippet:

all:
  vars:
    ssl_enabled: true
    rbac_enabled: true
    mds_ssl_mutual_auth_enabled: true
    # super user credentials for bootstrapping RBAC within Confluent Platform
    mds_super_user: mds
    mds_super_user_password: password
    # LDAP users for Confluent Platform components
    kafka_broker_ldap_user: kafka_broker
    kafka_broker_ldap_password: password
    schema_registry_ldap_user: schema_registry
    schema_registry_ldap_password: password
    kafka_connect_ldap_user: connect_worker
    kafka_connect_ldap_password: password
    ksql_ldap_user: ksql
    ksql_ldap_password: password
    kafka_rest_ldap_user: rest_proxy
    kafka_rest_ldap_password: password
    control_center_ldap_user: control_center
    control_center_ldap_password: password

kafka_broker:
  vars:
    kafka_broker_custom_properties:
      ldap.java.naming.factory.initial: com.sun.jndi.ldap.LdapCtxFactory
      ldap.com.sun.jndi.ldap.read.timeout: 3000
      ldap.java.naming.provider.url: ldap://ldap1:389
      ldap.java.naming.security.principal: uid=mds,OU=rbac,DC=example,DC=com
      ldap.java.naming.security.credentials: password
      ldap.java.naming.security.authentication: simple
      ldap.user.search.base: OU=rbac,DC=example,DC=com
      ldap.group.search.base: OU=rbac,DC=example,DC=com
      ldap.user.name.attribute: uid
      ldap.user.memberof.attribute.pattern: CN=(.*),OU=rbac,DC=example,DC=com
      ldap.group.name.attribute: cn
      ldap.group.member.attribute.pattern: CN=(.*),OU=rbac,DC=example,DC=com
      ldap.user.object.class: account

Run the confluent.platform.all playbook:
```
ansible-playbook -i <your hosts file> confluent.platform.all \
  --skip-tags package \
  -e deployment_strategy=parallel
```
Include the --skip-tags package option to skip the package installation tasks and to ensure no upgrade happens. The option also speeds up the reconfiguration process.
