["Edoardo Comar (JIRA)" <ji...@apache.org>]

Edoardo Comar commented on KAFKA-4611:
--------------------------------------

Hi, I am not sure what you are asking is not covered already :

https://issues.apache.org/jira/browse/KAFKA-4292 proposes custom callback handlers (therefore you control how to check username and pwd).

https://issues.apache.org/jira/browse/KAFKA-4259 added the functionality of defining jaas configurations in the client config file.

https://issues.apache.org/jira/browse/KAFKA-4180 will add the functionality of allowing different jaas config in a single client process.

Please note that Kerberos login uses JAAS too.

> Currently there are two login mechanisms supported by kafka client.
> 1) Default Login / Abstract Login which uses JAAS authentication
> 2) Kerberos Login
> Supporting user defined login mechanism's would be nice. 
> This could be achieved by removing the limitation from [here](https://github.com/apache/kafka/blob/0.10.0/clients/src/main/java/org/apache/kafka/common/security/authenticator/LoginManager.java#L44) ... Instead get custom login module implemented by user from the configs, gives users the option to implement custom login mechanism. 
> I am running into an issue in setting JAAS authentication system property on all executors of my spark cluster. Having custom mechanism to authorize kafka would be a good improvement for me
