[jira] [Created] (KAFKA-19444) SASL GSSAPI now working with librdkafka and AK 4.x

Emanuele Sabellico created KAFKA-19444:
------------------------------------------

             Summary: SASL GSSAPI now working with librdkafka and AK 4.x
                 Key: KAFKA-19444
                 URL: https://issues.apache.org/jira/browse/KAFKA-19444
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 4.0.0
            Reporter: Emanuele Sabellico


When testing librdkafka with AK 4.0 we see that SASL GSSAPI isn't working.
The feature is missing because it's incorrectly checking for JoinGroup v0 only and not v0+.

When testing librdkafka versions with 4.0 we missed this case so JoinGroup v0 and v1 were removed.

A [fix|https://github.com/confluentinc/librdkafka/pull/5131] is already merged in librdkafka and will be released in v2.11.0.
For rest of users the RPC versions should be added again to avoid having to upgrade the clients.
