This KIP proposes to add a new broker configuration connection.failed.authentication.delay.ms
which specifies the amount of time (in milliseconds) to delay a failed authentication response and subsequent socket disconnection by. In general, this must be configured to be lower than the underlying network protocol timeout request.timeout.ms
.
Configuration Name: connection.failed.authentication.delay.ms
Type: LongINT
Explanation: This configuration specifies the amount of time in milliseconds by which a response to a failed authentication will be delayed by.
Default Value: 0100
Priority: LOW
Proposed Changes

Compatibility, Deprecation, and Migration Plan
This The change in this KIP is backward compatible - the default value for the parameter will be set to 0ms which is the same behavior as without the changes in this KIPas it does not change the protocol in any way. The only difference is that clients will see a 100ms delay on failed authentications.
Rejected Alternatives
None.
