---------------------------------------
stanislavkozlovski opened a new pull request #5738: KAFKA-7478: Reduce default
logging verbosity in OAuthBearerLoginModule
URL: https://github.com/apache/kafka/pull/5738
The default `OAuthBearerLoginModule` is too noisy. My reasoning is that:
- Successful logins should be shown in `DEBUG`
- DEBUG should not be too noisy either
- Login aborted should be in `DEBUG` since authentication failures are
always logged

> The OAuthBearerLoginModule is pretty verbose by default and this fills logs
> in with too much information. It would be nice if we could reduce the
> verbosity by default and let the user opt in to inspect these debug-friendly
