SASL configuration maybe wrong?

Hey team.

I'm not sure if the documentation is outdated but if I use how it is:

...
sasl: %{
      mechanism: :plain,
      login: System.get_env("KAFFE_PRODUCER_USER"),
      password: System.get_env("KAFFE_PRODUCER_PASSWORD")
    }
...

It doesn't work. But, when use user instead of login it does:

    sasl: %{
      mechanism: :plain,
      user: System.get_env("KAFFE_PRODUCER_USER"),
      password: System.get_env("KAFFE_PRODUCER_PASSWORD")
    }
