When applying Kafka as target for Qlik Replicate, we found that customer's Kafka environment only supports the OAUTHBEARER authentication by default. However, currently the replicate only supports Certificate, Kerberos (SASL/GSSAPI), SASL/PLAIN, SASL/SCRAM-SHA-256, and SASL/SCRAM-SHA-512.
Therefore, we would like to suggest adding the OAUTHBEARER authentication for Kafka endpoint in the future release of Qlik Replicate.
