kafkacat在我看来，在执行 klist后一切正常的主机上看起来也很有趣和奇怪，向我展示了 3 张票：
$ klist
Ticket cache: FILE:/tmp/krb5cc_1000
Default principal: Pavel_Alexeev@PETERSBURG.EXAMPLE.COM
Valid starting Expires Service principal

但同时，如果我更改参数 '-Xsasl.kerberos.kinit.cmd=/usr/bin/kinit --use-referrals --password-file=/conf/paswd Pavel_Alexeev@PETERSBURG.EXAMPLE.COM; klist'我看到只有一张票！例如：
$ podman run --rm -it --name kafkacat-DEV \
-v$(pwd)/conf/integration:/conf -v$(pwd)/conf/integration/krb5.conf:/etc/krb5.conf \
localhost/kafkacat_gssapi_heimdal:3 \

所以我不明白另外两个来自哪里
在容器中执行后的列表kafkacat也只显示一个主体。
将不胜感激任何帮助。
PS 也将其报告为cyrus-sasl问题
