> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 2.0.0
> Reporter: Alexandre GRIFFAUT
> Priority: Major
> Labels: patch-available
> Fix For: 3.4.0
>
>
> Context
> On a multi-tenant secured cluster, with many consumers, a call to ListGroups
> api will log an authorization error for each consumer group of other tenant.
> Reason
> The handleListGroupsRequest function first tries to authorize a DESCRIBE
> CLUSTER, and if it fails it will then try to authorize a DESCRIBE GROUP on
> each consumer group.
> Fix
> In that case neither the DESCRIBE CLUSTER, nor the DESCRIBE GROUP of other
> tenant were intended, and should be specified in the Action using
> logIfDenied: false
