---------------------------------------
rajinisivaram opened a new pull request #5586: KAFKA-7338: Specify AES-128
default encryption type for Kerberos tests
URL: https://github.com/apache/kafka/pull/5586
Java 11 uses `aes256-cts-hmac-sha1-96` as the default encryption type for
Kerberos even if 256-bit encryption is not enabled. Configure
`default_tkt_enctypes` and `default_tgs_enctypes` to use AES-128 for Kerberos
tests.
