1. We currently support the Kafka scaler
    2. The Kafka scaler supports kerberos/GSSAPI
    3. In order to use kerberos you need to inject a keytab 
    4. In order to inject a keytab you need to mount a volume, i.e. https://keda.sh/docs/2.15/scalers/apache-kafka/#saslgssapi-in-manageryaml 
    5. You can't add a volume to the keda pods because the kedacontroller doesn't support those fields (so you either have to disable the CMA operator and hand-edit it, or you can't use it) 
    
TL;DR we supposedly support kerberos w/ the Kafka scaler, but it's impossible to configure currently. 

    All

    Every time

    1. Try to do https://keda.sh/docs/2.15/scalers/apache-kafka/#saslgssapi-in-manageryaml
    2. Notice you can't with CMA :( 
    3. Be sad. 
    

    Sadness and disappointment
