------------------------------------------
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.
