Hi,
Answering the questions:
I think Confluent allows the Kafka protocol, so I’d check the following documentation sections and Denodo KB articles: [Kafka Listeners](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/kafka_listeners/kafka_listeners) section of VirtualDataport Administration Guide and the articles located in the tag [Kafka](https://community.denodo.com/kb/en/tag/Kafka) of theDenodo Community.
About your second, I’d open separate topics in separate questions but regarding the LDAP, I use to check the [LDAP](https://community.denodo.com/kb/en/tag/LDAP) section of the Denodo Community and [LDAP Authentication](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/server_configuration/server_authentication/ldap_authentication/ldap_authentication) section of the Virtual DataPort Administration Guide.
Hope this helps!
