Hi Niels,
Thank you for making a submission to improve NiFi. I totally understand
your concern that the logs can be busy with these messages when you have a high
number of users connecting. To even need to deal with this situation means
you're using NiFi in a productive manner. However, we find that this message in
particular is extremely helpful in debugging for users who are not as
successful in configuring and using the application. Being able to identify the
attempted authentication requests without having to walk them through making
substantial configuration changes allows faster and more detailed responses.
However, I definitely empathize with your situation. Can I suggest making a
local change in your `$NIFI_HOME/conf/logback.xml` file? Two possible solutions
are changing the log level of the entire package to be `WARN`, as you seem to
have a good handle on the application and don't need informational alerts on
successful actions, or elevating the log level for that specific class while
retaining `INFO` messages for the other actions in that package.
## Option 1:
Replace
<logger name="org.apache.nifi.web.security" level="INFO"
additivity="false">
<appender-ref ref="USER_FILE"/>
</logger>
with
<logger name="org.apache.nifi.web.security" level="WARN"
additivity="false">
<appender-ref ref="USER_FILE"/>
</logger>
## Option 2:
Add
<logger name="org.apache.nifi.web.security.NiFiAuthenticationFilter"
level="WARN" additivity="false">
<appender-ref ref="USER_FILE"/>
</logger>
Either of these two solutions should improve your situation while still
allowing the community to easily support people who need a bit more help.
Thanks.

> The NiFiAuthenticationFilter polluting the logs with many "Authentication
> success" messages. I think those should be changed to debug level to reduce
> the amount of logging.
> Currently, we have more than one of those lines per second, due to multiple
> users actively using Nifi, which seems unneccesary.
