Hello Kudu Jenkins, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/6137 to look at the new patch set (#5). Change subject: [security] Add per-connection nonce for Kerberos replay resistance ...................................................................... [security] Add per-connection nonce for Kerberos replay resistance Kerberos is suceptible to replay attacks, which it attempts to mitigate by using a server-side replay cache. The cache is not 100% effective, and is extremely slow. This commit introduces an effective and efficient method of mitigating replay attacks by using a server-generated nonce which the client must send back to the server, wrapped in SASL integrity protection. This will allow Kudu to disable the replay cache without negatively affecting security. No tests are provided, but the codepath is well covered by existing Kerberos negotiation tests. I intend to write simulated mitm tests to check this and the channel binding protections soon.
