Confluent-kafka-dotnet: Error while setting up SASL/SCRAM on windows 10

[ietvijay]

Description

I am trying to setup SASL/SCRAM authentication to implement secure communication between client and brokers. But i am getting error while running following command on windows 10 machine.

bin\windows\kafka-configs.bat --zookeeper localhost:2181 --alter --add-config 'SCRAM-SHA-256=[iterations=8192,password=alice-secret],SCRAM-SHA-512=[password=alice-secret]' --entity-type users --entity-name alice

console log -

requirement failed: Unknown Dynamic Configuration: Set('SCRAM-SHA-256).

How to reproduce

1. Install Kafka binary from Kafka.org

2. Run Zookeeper and Server
   -> bin\windows\zookeeper-server-start.bat config\zookeeper.properties
   ->bin\windows\kafka-server-start.bat config\server.properties

3. try to setup scram credential for a user

->bin\windows\kafka-configs.bat --zookeeper localhost:2181 --alter --add-config 'SCRAM-SHA-256=[iterations=8192,password=alice-secret],SCRAM-SHA-512=[password=alice-secret]' --entity-type users --entity-name alice

Error:- you will get following error on cmd.
"requirement failed: Unknown Dynamic Configuration: Set('SCRAM-SHA-256)".

It's probably not a good idea to run the kafka brokers on windows - not many people do this and it's not well tested. To be clear though: this .NET client is tested and supported on Windows.

What you're trying to do aligns with the docs, so my best guess is a platform specific issue.

Remove ' from the command.

Here is working command:
bin\windows\kafka-configs.bat --zookeeper localhost:2181 --alter --add-config SCRAM-SHA-256=[iterations=8192,password=alice-secret],SCRAM-SHA-512=[password=alice-secret] --entity-type users --entity-name alice

I have used the command to create users for my Kafka clusters from Windows.
