I found some useful for auth with keycloak. we can authticate with keycloak and use rbac with oauth .

---

auth:
type: OAUTH2
oauth2:
client:
keycloak:
clientId: xxx
clientSecret: yyy
scope: openid
issuer-uri: https://<keycloak_instance>/auth/realms/
user-name-attribute: preferred_username
client-name: keycloak
provider: keycloak
custom-params:
type: keycloak

this custom parms to change
custom-params:
type: oauth
roles-field: roles

for rbac

rbac:
roles:
- name: "kafka-admin"
clusters:
- local-kafka
subjects:
- provider: oauth
type: user
value: "user1"
- provider: oauth
type: user
value: "user2"
permissions:
- resource: topic
value: ".*"
actions:
- VIEW
- MESSAGES_READ

    - resource: consumer
      value: ".*"
      actions: [ view ]

    - resource: schema
      value: ".*"
      actions: [ view ]

    - resource: connect
      value: ".*"
      actions: [ view ]

    - resource: acl
      value: ".*"
      actions: [ view ]

This can work only for specific user not for group with kafka. but this is useful before group rbac with keycloak.
