Proven Provenzano 38c409cf33 KAFKA-14084: SCRAM support in KRaft. (#13114) ... This commit adds support to store the SCRAM credentials in a cluster with KRaft quorum servers and no ZK cluster backing the metadata. This includes creating ScramControlManager in the controller, and adding support for SCRAM to MetadataImage and MetadataDelta. Change UserScramCredentialRecord to contain only a single tuple (name, mechanism, salt, pw, iter) rather than a mapping between name and a list. This will avoid creating an excessively large record if a single user has many entries. Because record ID 11 (UserScramCredentialRecord) has not been used before, this is a compatible change. SCRAM will be supported in 3.5-IV0 and later. This commit does not include KIP-900 SCRAM bootstrapping support, or updating the credential cache on the controller (as opposed to broker). We will implement these in follow-on commits. Reviewers: Manikumar Reddy <manikumar.reddy@gmail.com>, Colin P. McCabe <cmccabe@apache.org>		2023-03-03 10:23:34 -08:00
